Permission failures on target tables halt logical replication

Logical replication operations fail and stop when the subscription owner role lacks required privileges on target tables. Operations are executed with the subscription owner's privileges, so insufficient INSERT, UPDATE, DELETE, or TRUNCATE permissions cause replication conflicts.

Grant necessary permissions to the subscription owner role on all target tables. Review GRANT statements for INSERT, UPDATE, DELETE, and TRUNCATE on subscriber tables. Check subscriber server logs for permission-denied errors. Ensure subscription owner has appropriate privileges before initializing replication.
