Does PostgreSQL Work With Netlify?

Partially CompatibleLast verified: 2026-02-26

PostgreSQL works with Netlify, but requires external hosting since Netlify doesn't provide managed databases—you'll connect via serverless functions to a remote PostgreSQL instance.

How PostgreSQL Works With Netlify

PostgreSQL and Netlify don't have a native integration, but they work together effectively through Netlify Functions (serverless Node.js/Go backends). Your PostgreSQL database must be hosted separately—on platforms like AWS RDS, Heroku Postgres, Railway, or Supabase—and accessed via connection strings stored in Netlify environment variables. Netlify Functions can query your PostgreSQL database just like any Node.js server would, making it suitable for APIs, form handling, and dynamic content generation. The architecture is straightforward: your frontend deploys to Netlify's edge network, functions handle business logic, and they connect to your external PostgreSQL instance. This separation means you get Netlify's global CDN and zero-ops deployment while maintaining a persistent, queryable database elsewhere.

Best Use Cases

→Building JAMstack applications with dynamic data (blogs, e-commerce, SaaS dashboards)

→Creating serverless REST APIs that query PostgreSQL without managing servers

→Real-time form submissions and user authentication stored in PostgreSQL

→Scheduled database operations using Netlify Functions with cron job triggers

Quick Setup

bash

npm install pg

typescript

// netlify/functions/query-posts.ts
import { Handler } from '@netlify/functions';
import { Pool } from 'pg';

const pool = new Pool({
  connectionString: process.env.DATABASE_URL,
});

export const handler: Handler = async (event) => {
  try {
    const result = await pool.query(
      'SELECT id, title, content FROM posts LIMIT 10'
    );
    return {
      statusCode: 200,
      body: JSON.stringify(result.rows),
    };
  } catch (error) {
    return {
      statusCode: 500,
      body: JSON.stringify({ error: error.message }),
    };
  }
};

Known Issues & Gotchas

warning

Cold starts on serverless functions create latency for database queries

Fix: Use connection pooling (PgBouncer, Supabase connection pooling) and consider keeping functions warm with periodic pings for critical endpoints

critical

PostgreSQL connection limits exhausted by concurrent Netlify Function invocations

Fix: Implement connection pooling middleware (node-postgres with pools, or use managed solutions like Supabase that handle this)

critical

Environment variables with database credentials can be exposed in client-side code

Fix: Only use database credentials in Functions (server-side), never in frontend code; use Netlify's environment variable UI

info

No built-in database migrations or schema management in Netlify

Fix: Use tools like Flyway, Liquibase, or manage migrations separately in your deployment pipeline

Alternatives

•Vercel + PostgreSQL (Vercel Postgres for managed option, similar architecture)
•AWS Lambda + Amazon RDS PostgreSQL (more control, steeper learning curve)
•Firebase + Cloud Firestore (managed NoSQL alternative, no PostgreSQL setup needed)
