Hi hackers, while working on the new system catalog pg_wait_event (see [1]) I noticed that some wait events are currently "duplicated":
postgres=# select wait_event_name,count(*) from pg_wait_event group by wait_event_name having count(*) > 1; wait_event_name | count -----------------+------- SyncRep | 2 WALWrite | 2 (2 rows) Indeed: SynRep currently appears in "IPC" and "LWLock" (see [2]) WALWrite currently appears in "IO" and "LWLock" (see [2]) I think that can lead to confusion and it would be better to avoid duplicate wait event name across Wait Class (and so fix those 2 ones above), what do you think?
