Designing Postgres Row-Level Security (RLS) policies for multi-tenant authorization, especially in Supabase / PostgREST stacks — CREATE POLICY syntax, USING vs WITH CHECK, PERMISSIVE/RESTRICTIVE merge semantics, the (SELECT auth.uid()) performance pattern that turns 171ms scans into <1ms, indexes still required, role-based bypass via BYPASSRLS, security-definer escape hatches. Grounded in postgresql.org, Supabase docs, and Gary Austin's RLS-Performance benchmarks.
