You missed the point entirely. Relocating the code to some other file
wouldn't change the objection: the problem is that fd.c mustn't invoke
any transactional facilities such as catalog lookups. It's too low
level for that.
You could perhaps do it the other way around: some transactional
code (eg the assign hook for a GUC variable) tells fd.c to save
some private state controlling future temp file creations.
ok. i have done that.
I know this is not the time i told you but i was busy at job.
i haven't did anything about RemovePgTempFiles() yet, because i want
to know of the posibility of getting this on 8.3
