To create safe Supabase migrations, you must enable Row Level Security and define explicit policies for SELECT, INSERT, and UPDATE operations. Scoping access with auth.uid() checks ensures strict per-row authorization boundaries for multi-tenant production use.

The best way to write RLS policies for multi-tenant Supabase tables is to enforce auth.uid() checks on INSERT and UPDATE paths while applying explicit SELECT policies. This prevents over-permissioning and maintains intentional, auditable read/write access.

Validating Supabase security policies after a database migration involves running security advisor checks to confirm schema correctness. This post-migration validation ensures your RLS rules and explicit policies are properly enforced without exposing unprotected data.

Yes, you need to regenerate TypeScript types after modifying a Supabase schema. When schema changes occur during a migration, updating your TypeScript types ensures your application code remains synchronized with the new database structure and security policies.

Supabase INSERT policies allow unauthorized row access when they lack explicit auth.uid() checks for user-scoped tracking. Over-permissioning occurs if you do not enforce deterministic authorization boundaries and define strict per-row access rules for multi-tenant tables.
