# Backup production database first
pg_dump -h localhost -U postgres nchat > backup_$(date +%Y%m%d).sql

# Run migration
cd .backend/migrations
psql -h localhost -U postgres -d nchat -f 012_advanced_messaging_features.sql

# Verify tables
psql -h localhost -U postgres -d nchat -c "\dt nchat.nchat_message*"
psql -h localhost -U postgres -d nchat -c "\dt nchat.nchat_starred*"

# Verify triggers
psql -h localhost -U postgres -d nchat -c "SELECT * FROM pg_trigger WHERE tgname = 'message_edit_history_trigger';"

# Test helper functions
psql -h localhost -U postgres -d nchat -c "SELECT * FROM nchat.get_user_starred_messages('test-user-id', 10, 0);"

1. Open Hasura Console: http://api.localhost/console
2. Track new tables:
   • nchat_message_edit_history
   • nchat_starred_message
   • nchat_message_read_receipt
   • nchat_thread_subscription
3. Configure relationships:
   • message_edit_history.message → nchat_message
   • message_edit_history.user → nchat_user
   • starred_message.message → nchat_message
   • starred_message.user → nchat_user
   • Similar for read receipts
4. Set permissions:
   • message_edit_history: Select by message owner or admins
   • starred_message: Users can only see their own
   • message_read_receipt: Message sender can see all, others see own
5. Test GraphQL mutations in Hasura API Explorer
