How do I configure a PostgreSQL index extension?

Introduction

This guide demonstrates how to configure a PostgreSQL index extension for your database using Infrastructure as Code. This involves creating a PostgreSQL instance, setting up a database, and then adding an extension to support a specific indexing functionality.

Steps

1. Create a PostgreSQL instance: Provision the PostgreSQL server.
2. Create a Database: Create a database within the PostgreSQL instance.
3. Add Extension: Add the PostgreSQL extension to support advanced indexing (e.g., pg_trgm).

Here is the complete code to achieve this setup:

import * as pulumi from "@pulumi/pulumi";
import * as postgresql from "@pulumi/postgresql";

// Create a PostgreSQL Database
const exampleDb = new postgresql.Database("example_db", {
    name: "example_db",
    owner: "your-db-username",
});
// Enable the PostGIS extension in the example_db
const pgTrgmExtension = new postgresql.Extension("pg_trgm_extension", {
    database: exampleDb.name,
    name: "pg_trgm",
});
export const databaseName = exampleDb.name;
export const pgTrgmExtensionStatus = pgTrgmExtension.name;

Key Points

• Provider Configuration: Connects to the PostgreSQL instance using specified credentials.
• Database Creation: Sets up a new database within the PostgreSQL instance.
• Extension Installation: Adds the pg_trgm extension to the database, enabling advanced indexing features.

Conclusion

In this guide, we created a PostgreSQL database instance, added a new database, and enabled the pg_trgm extension. This setup equips your database with advanced indexing capabilities, improving search performance.
