Not sure.  It does already contain the ability to dump pg_control, but
that seems like rather a wart (not to mention redundant with
pg_controldata) because you have to explicitly say -c to get it to
realize that's what you want.  Map files would have to be another
special switch I think.

Yeah, that's been on the to-do list for awhile.  There's not a way that
pg_filedump could automatically recognize such files, is there?
