Does this skill handle Row Level Security (RLS)?

Yes, it includes patterns for enabling RLS on both database tables and realtime messages to ensure users only see data they are authorized to access.

What is the difference between Broadcast and Postgres Changes?

Postgres Changes listen to actual database modifications, while Broadcast is for ephemeral, client-to-client messaging that does not need to be stored in a table.

Can I filter specific database changes?

Absolutely. The skill provides syntax for filtering events by operation type (INSERT/UPDATE/DELETE) and specific column values like status or user IDs.

Is this skill compatible with React?

Yes, it includes optimized React hook patterns for managing the subscription lifecycle and cleaning up channels to prevent memory leaks.
