Closes #12.
The RLS policies call
auth.uid()directly inUSING/WITH CHECK, which Postgres re-evaluates once per row. This wraps each call in(select auth.uid())so the planner evaluates it once per statement (an InitPlan) and caches it -- the Supabase-documented RLS perf pattern.(select auth.uid())returns the same value, so row visibility is unchanged.20260628000000_wrap_rls_perf_initplan.sql); the SQL ispgrls fix --rule PERF001output.Happy to adjust the migration filename/placement to your conventions.
