Optimize Postgres queries by applying indexing, partitioning, and configuration tuning rules. Use concrete SQL examples to correct inefficient patterns, validating schema changes to ensure faster query execution in production environments.

Row Level Security (RLS) in Supabase isolates multi-tenant data by applying security policies directly to tables. Implementing RLS ensures reliable performance while enforcing strict data access controls across tenant boundaries.

Use table partitioning in PostgreSQL to optimize large tables by dividing them into smaller segments. Partitioning improves query performance and maintenance by allowing the database to scan only relevant data partitions.

These Postgres best practices apply to both Supabase environments and custom PostgreSQL deployments. The guidelines cover universal configuration tuning, indexing, and maintenance rules applicable across standard Postgres instances.

Supabase database queries may remain slow despite indexes if schemas are inefficient or configurations need tuning. Compare incorrect versus correct query patterns and apply maintenance routines to resolve performance bottlenecks.
