Hi all,
The attached patch is a continuation of Robert's work [1].
I made some changes:
- use of Latches instead of pg_usleep, so we don't have to wakeup regularly.
- call HandleStartupProcInterrupts() before CheckForStandbyTrigger()
because might change the trigger file's location
- compute recoveryUntilDelayTime in XLOG_XACT_COMMIT and
XLOG_XACT_COMMIT_COMPACT checks
- don't care about clockdrift because it's an admin problem.
Regards,
