+1. I'm interested in the feature.
This is just a example and it probable be useful for other users.
IMO, at
least, it's better to improve the specification that "Extension"
wait event type has only the "Extension" wait event.
I hope that nobody would counter-argue you here. In my opinion, we
should just introduce an API that allows extensions to retrieve wait
event numbers that are allocated by the backend under
PG_WAIT_EXTENSION, in a fashion similar to GetNamedLWLockTranche().
Say something like:
int GetExtensionWaitEvent(const char *wait_event_name);
+1, that's something I've in mind to work on once/if this patch is/get
committed.
Thanks for replying. If you are ok, I'll try to make a patch
to allow extensions to define custom wait events.
