FAQPage Schema
How do I set up RLS policies for multi-tenant data isolation in Supabase?

Multi-tenant data isolation in Supabase is achieved by applying Row Level Security (RLS) policies to standardize access controls. This ensures secure data separation by restricting row-level visibility based on tenant context and user roles.

What is the best way to run zero-downtime database migrations in Supabase?

Zero-downtime database migrations in Supabase require clear naming conventions and robust rollback strategies. Following vetted PostgreSQL patterns ensures schema changes are applied safely without locking tables or disrupting active multi-tenant deployments.

How does indexing affect query optimization and performance in PostgreSQL?

Proper indexing directly improves query optimization and PostgreSQL performance by accelerating data retrieval. Applying targeted index patterns reduces scan times and enhances overall database reliability under heavy query loads.

Can I use pg_cron for scheduling operational tasks in Supabase?

Yes, pg_cron is supported for scheduling operational tasks in Supabase deployments. It enables secure execution of recurring database maintenance jobs, automating routine operational guidance directly within the PostgreSQL environment.

Why are my Supabase queries slow despite having indexes?

Slow Supabase queries despite existing indexes often stem from inefficient query structures or missing targeted index patterns. Reviewing query optimization guidelines helps identify bottlenecks and apply proper indexing for improved performance.
