PostgreSQL Query

Optimization Tips

1.Avoid SELECT * — specify only needed columns to reduce I/O.
2.OR conditions may prevent index usage. Consider UNION ALL for separate indexed lookups.
3.Functions on indexed columns in WHERE prevent index scans. Store normalized values or use expression indexes.
4.Large OFFSET values are expensive in PostgreSQL. Use keyset pagination (WHERE id > last_id).

Run EXPLAIN (ANALYZE, BUFFERS) in psql for detailed execution plans.
