If we're going to do some renaming, then I suggest we do a
mini-file-system structure under $PGDATA, like

$PGDATA/etc
$PGDATA/log
$PGDATA/run (lock files etc.)
$PGDATA/tmp
$PGDATA/var

The names of all the things under "var" could still be refined, but it's
much less likely that users will confuse data with configuration or
plain logs under that scheme.
