SIGSEGV when anon role calls SECURITY DEFINER function without EXECUTE via PostgREST LATERAL CTE on local Supabase stack
Local Supabase backend crashes with signal 11 when the anon role calls a SECURITY DEFINER function via PostgREST RPC after EXECUTE has been revoked from anon. The crash occurs inside PostgreSQL during permission error handling inside a LATERAL join, and is triggered by the supautils extension's hint_roles feature configured to include 'anon'.
