Row Level Security (RLS)

RLS controls data access at the row level based on the authenticated user.

Enabling RLS

alter table public.posts enable row level security;

Policy Types

Operation	Clause	Purpose
SELECT	`using`	Filter which rows can be read
INSERT	`with check`	Validate new rows
UPDATE	`using` + `with check`	Filter + validate
DELETE	`using`	Filter which rows can be deleted

Common Policy Patterns

1. User owns row:

create policy "Users can view own data" on profiles
to authenticated
using ( (select auth.uid()) = user_id );

create policy "Users can update own data" on profiles
to authenticated
using ( (select auth.uid()) = user_id )
with check ( (select auth.uid()) = user_id );

2. Public read, owner write:

create policy "Public read" on posts
for select using (true);

create policy "Owner can modify" on posts
for all to authenticated
using ( (select auth.uid()) = author_id );

3. Team/organization access:

create policy "Team members can view" on documents
to authenticated
using (
  team_id in (
    select team_id from team_members
    where user_id = (select auth.uid())
  )
);

4. Role-based access:

create policy "Admins can do anything" on posts
to authenticated
using (
  exists (
    select 1 from users
    where id = (select auth.uid()) and role = 'admin'
  )
);

RLS Performance Tips

Always use (select auth.uid()) instead of auth.uid():

-- SLOW (recalculates per row)
using ( auth.uid() = user_id )

-- FAST (calculates once, 99%+ improvement)
using ( (select auth.uid()) = user_id )

Add indexes on RLS columns:

create index idx_posts_user_id on posts using btree (user_id);
create index idx_documents_team_id on documents using btree (team_id);

Specify roles with TO:

-- Good: policy only applies to authenticated users
create policy "..." on posts to authenticated using (...);

-- Bad: policy applies to all roles including anon
create policy "..." on posts using (...);

Viewing Policies

select schemaname, tablename, policyname, permissive, roles, cmd, qual, with_check
from pg_policies
where tablename = 'your_table';
