Implemented `SendWALHeartbeat()` method to maintain PostgreSQL WAL activity. To ensure consistent WAL activity in idle PostgreSQL databases and prevent indefinite growth of replication slots, a heartbeat mechanism is introduced. This method generates WAL activity by creating and immediately dropping an aggregate function, ensuring a guaranteed and lightweight WAL entry without leaving persistent changes in the database schema. Using an aggregate was chosen for its guaranteed WAL generation and minimal impact. fixes: #429
