I believe we do not call RemovePgTempFiles during a crash recovery
cycle; this is intentional on the theory that the temp files might
contain useful debugging clues.
So there is a potential problem there.
Not sure how important it really is though --- neither crashes nor
tablespace drops ought to be so common that we need a really nice
While tablespace operations won't normally be a day-to-day thing,
it's not good if users can't delete a tablespace because it's not
empty, but can't find out what exactly is in the tablespace.
If there was a way for DBA's to know they could safely delete the
files (maybe the files timestamp is older than postmaster start;
sure how you measure that), then I think this would be enough to
give them a
the only semi-sane solution i can think of, is to have a superuser

still exists a chance for shoot yourself on the foot...

If we're saving data on crashes with the intention that it might be
useful then we need to be able to get a list of what those files are,
and possibly be able to delete them easily.
