PostgreSQL RLS policy creates infinite recursion loop

By PulseAugur Editorial · [1 sources] ·

A developer encountered an infinite recursion error in PostgreSQL's Row Level Security (RLS) policies while working with Supabase. The issue stemmed from a policy on the `public.cours` table that queried the `public.user_roles` table, which itself had policies that also queried `public.user_roles`. This created a loop when a new `agent_readonly` role was added to the `authenticated` membership, causing PostgreSQL to evaluate all permissive policies. The developer explored solutions like `SECURITY DEFINER` functions and role isolation before ultimately deciding to move role information out of the database and into JWT custom claims. AI
