# Azure.ResourceManager.PostgreSql (.NET)

## Overview

This public intake copy packages `plugins/antigravity-awesome-skills/skills/azure-resource-manager-postgresql-dotnet` from `https://github.com/sickn33/antigravity-awesome-skills` into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the `external_source` block in `metadata.json` plus `ORIGIN.md` as the provenance anchor for review.

# Azure.ResourceManager.PostgreSql (.NET) Azure Resource Manager SDK for managing PostgreSQL Flexible Server deployments.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Environment Variables, Authentication, SKU Tiers, PostgreSQL Versions, High Availability Modes, Error Handling.

## When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

- This skill is applicable to execute the workflow or actions described in the overview.
- Use when the request clearly matches the imported source intent: Azure PostgreSQL Flexible Server SDK for .NET. Database management for PostgreSQL Flexible Server deployments.
- Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
- Use when provenance needs to stay visible in the answer, PR, or review packet.
- Use when copied upstream references, examples, or scripts materially improve the answer.
- Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

## Operating Table

| Situation | Start here | Why it matters |
| --- | --- | --- |
| First-time use | `metadata.json` | Confirms repository, branch, commit, and imported path through the `external_source` block before touching the copied workflow |
| Provenance review | `ORIGIN.md` | Gives reviewers a plain-language audit trail for the imported source |
| Workflow execution | `SKILL.md` | Starts with the smallest copied file that materially changes execution |
| Supporting context | `SKILL.md` | Adds the next most relevant copied source file without loading the entire package |
| Handoff decision | `## Related Skills` | Helps the operator switch to a stronger native skill when the task drifts |

## Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

#### Imported: Core Workflows

### 1. Create PostgreSQL Flexible Server

```csharp
using Azure.ResourceManager.PostgreSql.FlexibleServers;
using Azure.ResourceManager.PostgreSql.FlexibleServers.Models;

ResourceGroupResource resourceGroup = await client
    .GetDefaultSubscriptionAsync()
    .Result
    .GetResourceGroupAsync("my-resource-group");

PostgreSqlFlexibleServerCollection servers = resourceGroup.GetPostgreSqlFlexibleServers();

PostgreSqlFlexibleServerData data = new PostgreSqlFlexibleServerData(AzureLocation.EastUS)
{
    Sku = new PostgreSqlFlexibleServerSku("Standard_D2ds_v4", PostgreSqlFlexibleServerSkuTier.GeneralPurpose),
    AdministratorLogin = "pgadmin",
    AdministratorLoginPassword = "YourSecurePassword123!",
    Version = PostgreSqlFlexibleServerVersion.Ver16,

    }
};

ArmOperation<PostgreSqlFlexibleServerResource> operation = await servers
    .CreateOrUpdateAsync(WaitUntil.Completed, "my-postgresql-server", data);

PostgreSqlFlexibleServerResource server = operation.Value;
Console.WriteLine($"Server created: {server.Data.FullyQualifiedDomainName}");
```

### 2. Create Database

```csharp
PostgreSqlFlexibleServerResource server = await resourceGroup
    .GetPostgreSqlFlexibleServerAsync("my-postgresql-server");

PostgreSqlFlexibleServerDatabaseCollection databases = server.GetPostgreSqlFlexibleServerDatabases();

PostgreSqlFlexibleServerDatabaseData dbData = new PostgreSqlFlexibleServerDatabaseData
{
    Charset = "UTF8",
    Collation = "en_US.utf8"
};

ArmOperation<PostgreSqlFlexibleServerDatabaseResource> operation = await databases
    .CreateOrUpdateAsync(WaitUntil.Completed, "myappdb", dbData);

PostgreSqlFlexibleServerDatabaseResource database = operation.Value;
Console.WriteLine($"Database created: {database.Data.Name}");
```

### 3. Configure Firewall Rules

```csharp
PostgreSqlFlexibleServerFirewallRuleCollection firewallRules = server.GetPostgreSqlFlexibleServerFirewallRules();

// Allow specific IP range
PostgreSqlFlexibleServerFirewallRuleData ruleData = new PostgreSqlFlexibleServerFirewallRuleData
{
    StartIPAddress = System.Net.IPAddress.Parse("10.0.0.1"),
    EndIPAddress = System.Net.IPAddress.Parse("10.0.0.255")
};

ArmOperation<PostgreSqlFlexibleServerFirewallRuleResource> operation = await firewallRules
    .CreateOrUpdateAsync(WaitUntil.Completed, "allow-internal", ruleData);

// Allow Azure services
PostgreSqlFlexibleServerFirewallRuleData azureServicesRule = new PostgreSqlFlexibleServerFirewallRuleData
{
    StartIPAddress = System.Net.IPAddress.Parse("0.0.0.0"),
    EndIPAddress = System.Net.IPAddress.Parse("0.0.0.0")
};

await firewallRules.CreateOrUpdateAsync(WaitUntil.Completed, "AllowAllAzureServicesAndResourcesWithinAzureIps", azureServicesRule);
```

### 4. Update Server Configuration

```csharp
PostgreSqlFlexibleServerConfigurationCollection configurations = server.GetPostgreSqlFlexibleServerConfigurations();

// Get current configuration
PostgreSqlFlexibleServerConfigurationResource config = await configurations
    .GetAsync("max_connections");

// Update configuration
PostgreSqlFlexibleServerConfigurationData configData = new PostgreSqlFlexibleServerConfigurationData
{
    Value = "500",
    Source = "user-override"
};

ArmOperation<PostgreSqlFlexibleServerConfigurationResource> operation = await configurations
    .CreateOrUpdateAsync(WaitUntil.Completed, "max_connections", configData);

// Common PostgreSQL configurations to tune
string[] commonParams = {
    "max_connections",
    "shared_buffers",
    "work_mem",
    "maintenance_work_mem",
    "effective_cache_size",
    "log_min_duration_statement"
};
```

### 5. Configure Entra ID Administrator

```csharp
PostgreSqlFlexibleServerActiveDirectoryAdministratorCollection admins =
    server.GetPostgreSqlFlexibleServerActiveDirectoryAdministrators();

PostgreSqlFlexibleServerActiveDirectoryAdministratorData adminData =
    new PostgreSqlFlexibleServerActiveDirectoryAdministratorData
{
    PrincipalType = PostgreSqlFlexibleServerPrincipalType.User,
    PrincipalName = "aad-admin@contoso.com",
    TenantId = Guid.Parse("<tenant-id>")
};

ArmOperation<PostgreSqlFlexibleServerActiveDirectoryAdministratorResource> operation = await admins
    .CreateOrUpdateAsync(WaitUntil.Completed, "<entra-object-id>", adminData);
```

### 6. List and Manage Servers

```csharp
// List servers in resource group
await foreach (PostgreSqlFlexibleServerResource server in resourceGroup.GetPostgreSqlFlexibleServers())
{
    Console.WriteLine($"Server: {server.Data.Name}");
    Console.WriteLine($"  FQDN: {server.Data.FullyQualifiedDomainName}");
    Console.WriteLine($"  Version: {server.Data.Version}");
    Console.WriteLine($"  State: {server.Data.State}");
    Console.WriteLine($"  SKU: {server.Data.Sku.Name} ({server.Data.Sku.Tier})");
    Console.WriteLine($"  HA: {server.Data.HighAvailability?.Mode}");
}

// List databases in server
await foreach (PostgreSqlFlexibleServerDatabaseResource db in server.GetPostgreSqlFlexibleServerDatabases())
{
    Console.WriteLine($"Database: {db.Data.Name}");
}
```

### 7. Backup and Point-in-Time Restore

```csharp
// List available backups
await foreach (PostgreSqlFlexibleServerBackupResource backup in server.GetPostgreSqlFlexibleServerBackups())
{
    Console.WriteLine($"Backup: {backup.Data.Name}");
    Console.WriteLine($"  Type: {backup.Data.BackupType}");
    Console.WriteLine($"  Completed: {backup.Data.CompletedOn}");
}

// Point-in-time restore
PostgreSqlFlexibleServerData restoreData = new PostgreSqlFlexibleServerData(AzureLocation.EastUS)
{
    CreateMode = PostgreSqlFlexibleServerCreateMode.PointInTimeRestore,
    SourceServerResourceId = server.Id,
    PointInTimeUtc = DateTimeOffset.UtcNow.AddHours(-2)
};

ArmOperation<PostgreSqlFlexibleServerResource> operation = await servers
    .CreateOrUpdateAsync(WaitUntil.Completed, "my-postgresql-restored", restoreData);
```

### 8. Create Read Replica

```csharp
PostgreSqlFlexibleServerData replicaData = new PostgreSqlFlexibleServerData(AzureLocation.WestUS)
{
    CreateMode = PostgreSqlFlexibleServerCreateMode.Replica,
    SourceServerResourceId = server.Id,
    Sku = new PostgreSqlFlexibleServerSku("Standard_D2ds_v4", PostgreSqlFlexibleServerSkuTier.GeneralPurpose)
};

ArmOperation<PostgreSqlFlexibleServerResource> operation = await servers
    .CreateOrUpdateAsync(WaitUntil.Completed, "my-postgresql-replica", replicaData);
```

### 9. Stop and Start Server

```csharp
PostgreSqlFlexibleServerResource server = await resourceGroup
    .GetPostgreSqlFlexibleServerAsync("my-postgresql-server");

// Stop server (saves costs when not in use)
await server.StopAsync(WaitUntil.Completed);

// Start server
await server.StartAsync(WaitUntil.Completed);

// Restart server
await server.RestartAsync(WaitUntil.Completed, new PostgreSqlFlexibleServerRestartParameter
{
    RestartWithFailover = true,
    FailoverMode = PostgreSqlFlexibleServerFailoverMode.PlannedFailover
});
```

### 10. Update Server (Scale)

```csharp
PostgreSqlFlexibleServerResource server = await resourceGroup
    .GetPostgreSqlFlexibleServerAsync("my-postgresql-server");

PostgreSqlFlexibleServerPatch patch = new PostgreSqlFlexibleServerPatch
{
    Sku = new PostgreSqlFlexibleServerSku("Standard_D4ds_v4", PostgreSqlFlexibleServerSkuTier.GeneralPurpose),
    Storage = new PostgreSqlFlexibleServerStorage
    {
        StorageSizeInGB = 256,
        Tier = PostgreSqlStorageTierName.P40
    }
};

ArmOperation<PostgreSqlFlexibleServerResource> operation = await server
    .UpdateAsync(WaitUntil.Completed, patch);
```

### 11. Delete Server

```csharp
PostgreSqlFlexibleServerResource server = await resourceGroup
    .GetPostgreSqlFlexibleServerAsync("my-postgresql-server");

await server.DeleteAsync(WaitUntil.Completed);
```

#### Imported: Environment Variables

```bash
AZURE_SUBSCRIPTION_ID=<your-subscription-id>
AZURE_RESOURCE_GROUP=<your-resource-group>
AZURE_POSTGRESQL_SERVER_NAME=<your-postgresql-server>
```

## Examples

### Example 1: Ask for the upstream workflow directly

```text
Use @azure-resource-manager-postgresql-dotnet-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
```

**Explanation:** This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

### Example 2: Ask for a provenance-grounded review

```text
Review @azure-resource-manager-postgresql-dotnet-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
```

**Explanation:** Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

### Example 3: Narrow the copied support files before execution

```text
Use @azure-resource-manager-postgresql-dotnet-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
```

**Explanation:** This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

### Example 4: Build a reviewer packet

```text
Review @azure-resource-manager-postgresql-dotnet-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.
```

**Explanation:** This is useful when the PR is waiting for human review and you want a repeatable audit packet.



## Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

- Use Flexible Server — Single Server is deprecated
- Enable zone-redundant HA — For production workloads
- Use DefaultAzureCredential — Prefer over connection strings
- Configure Entra ID authentication — More secure than SQL auth alone
- Enable both auth methods — Entra ID + password for flexibility
- Set appropriate backup retention — 7-35 days based on compliance
- Use private endpoints — For secure network access

#### Imported: Best Practices

1. **Use Flexible Server** — Single Server is deprecated
2. **Enable zone-redundant HA** — For production workloads
3. **Use DefaultAzureCredential** — Prefer over connection strings
4. **Configure Entra ID authentication** — More secure than SQL auth alone
5. **Enable both auth methods** — Entra ID + password for flexibility

7. **Use private endpoints** — For secure network access
8. **Tune server parameters** — Based on workload characteristics
9. **Use read replicas** — For read-heavy workloads
10. **Stop dev/test servers** — Save costs when not in use

## Troubleshooting

### Problem: The operator skipped the imported context and answered too generically

**Symptoms:** The result ignores the upstream workflow in `plugins/antigravity-awesome-skills/skills/azure-resource-manager-postgresql-dotnet`, fails to mention provenance, or does not use any copied source files at all.
**Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing.

### Problem: The imported workflow feels incomplete during review

**Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task.
**Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

### Problem: The task drifted into a different specialization

**Symptoms:** The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
**Solution:** Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
