Advances the current confirmed position of a replication slot named slot_name. The slot will not be moved backwards, and it will not be moved beyond the current insert location. Returns the name of the slot and the actual position that it was advanced to. The updated slot position information is written out at the next checkpoint if any advancing is done. So in the event of a crash, the slot may return to an earlier position. If the specified slot is a logical failover slot then the function will not return until all physical slots specified in synchronized_standby_slots have confirmed WAL receipt.

English manual coverage begins with PostgreSQL 7.1. Source history and runtime observations have their own recorded version boundaries.
