Heikki Linnakangas napsal(a):
The FSM is not updated during WAL replay. That means that after crash
recovery, the FSM won't be completely up-to-date, but at roughly the
state it was at last checkpoint. In a warm stand-by, the FSM will
reflect the situation at last full backup. We need to think when the FSM
should be updated during WAL replay. Probably not after every record,
because of the overhead, but certainly more often than never.
What's about after a page write during a WAL replay?
