If we're going to be renaming things, we might wish to consider further
changes, such as putting everything that's temporary & not WAL-logged
into "pgsql_tmp" directories, so we don't need lists of "directories to

We should really have an independent thread about this though, as it's
not what Robert's asking about here.
