Nah, I don't buy that one either. Nobody has any business creating any
non-Postgres files in the stats directory ... and if somebody does want
to stick a FIFO in there, perhaps for debug purposes, why should we stop
them?
The case with COPY is a bit different, since there it's reasonable to be
worried about collisions with other users' files --- but I agree with
Andres that this change would eliminate too many valid use-cases.
