10 PostgreSQL Performance Tips You Should Know

Optimize Your Database

PostgreSQL is powerful out of the box, but these tips will help you squeeze out even more performance.

1. Use EXPLAIN ANALYZE

EXPLAIN ANALYZE SELECT * FROM posts WHERE author_id = '...';

2. Create Proper Indexes

Index columns used in WHERE, JOIN, and ORDER BY clauses.

3. Use Partial Indexes

CREATE INDEX posts_published_idx ON posts(published_at) 
WHERE published = true;

4. Batch Your Inserts

Insert multiple rows in a single statement instead of one at a time.

5. Use Connection Pooling

Tools like PgBouncer can dramatically improve connection handling.

These optimizations can make your database 10x faster with minimal effort!
