Hi All,
monitoring.sgml file has the list of all the wait event names that is
being monitored by pg_stat_activity but as one of the LWLock named
'OldSnapshotTimemapLock' was added recently as the part of git commit
'848ef42b' -->"Add the "snapshot too old" feature", this lwlock
information is currently missing in the monitoring.sgml file. I have
added the necessary information about the same in this file and
attached is the patch. Thanks.
With Regards,
Ashutosh Sharma
