Supabase Postgres Best Practices
Apply Supabase-oriented Postgres rules: schema design, RLS, indexes, and safe migrations.
What it is
Supabase Postgres Best Practices keeps agents from inventing RLS policies that fail open, skipping indexes on filter columns, or shipping migrations that lock production tables. It is vendor guidance for real Supabase projects, not generic SQL trivia.
Example prompt
Lock the database
Add an orders table with RLS so users only see their own rows. Show the migration and policies.
