Note that 7.4 was pretty poor at recovering space from the catalogs
and the associated indexes.  It could be that you would need to shut
down each night and vacuum full the catalogs in single user mode to
recover the space.

But it's been a while since I ran something older than 8.1 or so, so
it might have been an even older version that had those issues.
