The idea that this code would know exactly what's what under $PGDATA
scares me. I can positively guarantee that it would diverge from reality
over time, and nobody would notice until it ate their data, failed to
start, or otherwise behaved undesirably.
pg_log/ is a perfect example, because that is not a hard-wired directory
name; somebody could point the syslogger at a different place very easily.
Wiring in special behavior for that name is just wrong.
I would *much* rather have a uniform rule for how to treat each file
the scan comes across. It might take some tweaking to get to one that
works well; but once we did, we could have some confidence that it
wouldn't break later.
