-- Fix: Allow users to insert their own subscription on signup
-- Run this in Supabase SQL Editor

-- Option 1: Add INSERT policy for self-signup
CREATE POLICY "user_subscriptions_insert_self" ON user_subscriptions 
FOR INSERT WITH CHECK (
  (SELECT auth.uid()) = user_id
);

-- Option 2 (better): Extend the existing handle_new_user trigger
-- This automatically creates subscription when user registers
CREATE OR REPLACE FUNCTION public.handle_new_user()
RETURNS trigger AS $$

  -- Create profile
