I've committed a patch to do the RequstXLogSwitch() before shutdown
checkpoint as discussed. It seems safe to me. (sorry for the delay, and
thanks for the reminder)
Not sure if that is a fix that will work in all cases.
There is a potential timing problem with when the archiver is shutdown:
that may now be fixed in 8.4, see what you think.
Can you elaborate?
Is the archiver still alive and working after the log switch occurs?
Yes.
If the archiver is working, but has fallen behind at the point of
shutdown, does the archiver operate for long enough to ensure we are
archived up to the point of the log switch prior to checkpoint?
Yes, it archives all pending WAL segments before exiting.
Ok, we're good then I guess.
