Supabase RLS Audit Checklist: Problem to Fix Production Guide

Run a repeatable RLS audit for Supabase policies, auth context, and query performance before incidents happen.

Tweetable Insight#

RLS audits are cheaper than post-mortems.

One-Sentence Definition#

An RLS audit verifies policy correctness, access scope, and query performance under real auth contexts.

Production Risk Warning#

Skipping audits causes silent overexposure or silent access denial in production.

Problem (Search Intent First)#

Teams struggle to know whether RLS policies are actually safe and complete.

Why It Happens#

Policy logic grows incrementally and coverage drifts from real access patterns.

Production-Grade Fix#

Use a repeatable SQL audit + checklist at every release.

Copy-Paste Solution#

sql
select schemaname, tablename, policyname, permissive, roles, cmd
from pg_policies
where schemaname = 'public'
order by tablename, policyname;

Edge Cases#

  • Policies can pass functional tests while failing under load.
  • Missing with check on updates creates data integrity gaps.
