Realtime Postgres RLS now available on Supabase

Realtime Postgres RLS is now available on Supabase, providing security improvements to the Realtime server by broadcasting database changes only to authenticated users while respecting the same PostgreSQL policies used for Row Level Security (RLS). This feature ensures that data access and visibility are controlled according to user permissions. The implementation of WALRUS (Write Ahead Log Realtime Unified Security) enables efficient querying to check access, reducing network latency and I/O bottlenecks while enhancing performance.
