Thanks for pointing that out. Next time we touch the scripts, I'll
see about using this instead of the bash script we call to do the
equivalent.
I don't suppose there's something which looks *into* a backup file
and deletes all WAL files not needed to restore the related base
backup? That would eliminate an even *uglier* bash script here.
