Permissions failures on subscriber cause replication conflicts

Logical replication operations run with the privileges of the subscription owner role. If the owner lacks permissions on target tables or if row-level security policies are enabled that reject operations, replication will fail with conflicts and stop.

Ensure subscription owner role has necessary permissions (INSERT, UPDATE, DELETE, TRUNCATE) on all target tables. Review row-level security policies on subscriber tables - they will be enforced for replication operations and can cause failures. Check subscriber server logs for permission-related errors. Grant appropriate privileges or adjust RLS policies to allow replication.
