Azure PostgreSQL for TypeScript (node-postgres) workflow skill. Use this skill when the user needs Connect to Azure Database for PostgreSQL Flexible Server from Node.js/TypeScript using the pg (node-postgres) package and the operator should preserve the upstream workflow, copied support files, and provenance before merging or handing off.
This public intake copy packages plugins/antigravity-awesome-skills/skills/azure-postgres-ts 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 PostgreSQL for TypeScript (node-postgres) Connect to Azure Database for PostgreSQL Flexible Server using the pg (node-postgres) package with support for password and Microsoft Entra ID (passwordless) authentication.
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, Pool with Entra ID Token Refresh, Error Handling, Connection String Format, Pool Events.
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: Connect to Azure Database for PostgreSQL Flexible Server from Node.js/TypeScript using the pg (node-postgres) package.
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

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.
Single Client Connection typescript import { Client } from "pg"; const client = new Client({ host: process.env.AZUREPOSTGRESQLHOST, database: process.env.AZUREPOSTGRESQLDATABASE, user: process.env.AZUREPOSTGRESQLUSER, password: process.env.AZUREPOSTGRESQLPASSWORD, port: 5432, ssl: { rejectUnauthorized: true } }); try { await client.connect(); const result = await client.query("SELECT NOW() as currenttime"); console.log(result.rows[0].currenttime); } finally { await client.end(); // Always close connection } ### 2.
Connection Pool (Recommended for Production) typescript import { Pool } from "pg"; const pool = new Pool({ host: process.env.AZUREPOSTGRESQLHOST, database: process.env.AZUREPOSTGRESQLDATABASE, user: process.env.AZUREPOSTGRESQLUSER, password: process.env.AZUREPOSTGRESQLPASSWORD, port: 5432, ssl: { rejectUnauthorized: true }, // Pool configuration max: 20, // Maximum connections in pool idleTimeoutMillis: 30000, // Close idle connections after 30s connectionTimeoutMillis: 10000 // Timeout for new connections }); // Query using pool (automatically acquires and releases connection) const result = await pool.query("SELECT FROM users WHERE id = $1", [userId]); // Explicit checkout for multiple queries const client = await pool.connect(); try { const res1 = await client.query("SELECT FROM users"); const res2 = await client.query("SELECT FROM orders"); } finally { client.release(); // Return connection to pool } // Cleanup on shutdown await pool.end(); ### 3.
Parameterized Queries (Prevent SQL Injection) typescript // ALWAYS use parameterized queries - never concatenate user input const userId = 123; const email = "user@example.com"; // Single parameter const result = await pool.query( "SELECT FROM users WHERE id = $1", [userId] ); // Multiple parameters const result = await pool.query( "INSERT INTO users (email, name, createdat) VALUES ($1, $2, NOW()) RETURNING ", [email, "John Doe"] ); // Array parameter const ids = [1, 2, 3, 4, 5]; const result = await pool.query( "SELECT FROM users WHERE id = ANY($1::int[])", [ids] ); ### 4.
import { Pool } from"pg";
const pool = newPool({
host: process.env.AZURE_POSTGRESQL_HOST,
database: process.env.AZURE_POSTGRESQL_DATABASE,
user: process.env.AZURE_POSTGRESQL_USER,
password: process.env.AZURE_POSTGRESQL_PASSWORD,
port: 5432,
ssl: { rejectUnauthorized: true },
// Pool configurationmax: 20, // Maximum connections in poolidleTimeoutMillis: 30000, // Close idle connections after 30sconnectionTimeoutMillis: 10000// Timeout for new connections
});
// Query using pool (automatically acquires and releases connection)const result = await pool.query("SELECT * FROM users WHERE id = $1", [userId]);
// Explicit checkout for multiple queriesconst client = await pool.connect();
try {
const res1 = await client.query("SELECT * FROM users");
const res2 = await client.query("SELECT * FROM orders");
} finally {
client.release(); // Return connection to pool
}
// Cleanup on shutdownawait pool.end();
3. Parameterized Queries (Prevent SQL Injection)
// ALWAYS use parameterized queries - never concatenate user inputconst userId = 123;
const email = "user@example.com";
// Single parameterconst result = await pool.query(
"SELECT * FROM users WHERE id = $1",
[userId]
);
// Multiple parametersconst result = await pool.query(
"INSERT INTO users (email, name, created_at) VALUES ($1, $2, NOW()) RETURNING *",
[email, "John Doe"]
);
// Array parameterconst ids = [1, 2, 3, 4, 5];
const result = await pool.query(
"SELECT * FROM users WHERE id = ANY($1::int[])",
[ids]
);
import { Pool, QueryResult } from"pg";
interfaceUser {
id: number;
email: string;
name: string;
created_at: Date;
}
// Type the query resultconstresult: QueryResult<User> = await pool.query<User>(
"SELECT * FROM users WHERE id = $1",
[userId]
);
constuser: User | undefined = result.rows[0];
// Type-safe insertasyncfunctioncreateUser(pool: Pool,
email: string,
name: string): Promise<User> {
const result = await pool.query<User>(
"INSERT INTO users (email, name) VALUES ($1, $2) RETURNING *",
[email, name]
);
return result.rows[0];
}

Examples
Example 1: Ask for the upstream workflow directly
Use @azure-postgres-ts-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
Review @azure-postgres-ts-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
Use @azure-postgres-ts-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
Review @azure-postgres-ts-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.

Imported: Best Practices
Always use connection pools for production applications
Use parameterized queries - Never concatenate user input
Always close connections - Use try/finally or connection pools
Handle token refresh - Entra ID tokens expire after ~1 hour
Set connection timeouts - Avoid hanging on network issues
Use transactions - For multi-statement operations
Monitor pool metrics - Track pool.totalCount, pool.idleCount, pool.waitingCount
Graceful shutdown - Call pool.end() on application termination
Use TypeScript generics - Type your query results for safety
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-postgres-ts, 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.
