I had this same problem with 7.1.x, even doing full vacuums on
SourceForge.net last year.
I assumed after a while that there was some hidden bug where file bloat
occurred, despite the vacuum. After 3 months or so, you'd have to
dump/restore the entire db and you'd be golden for a while again. After
the dump/restore process things seemed much snappier too, and vacuum ran
almost instantly.
I haven't verified if this problem still occurs in 7.2.x, using vacuum full.
