Sadly, in my case, the db is so busy that autovac processes run for weeks and
never catch up (insufficient h/w for the app quite frankly - the addition of
some more SSD drives have already helped). I eventually run up against the
wraparound wall and the only way forward is to stop everything and
dump/restore (vacuuming the entire db would take an unknown period of N x
weeks - dumping/restoring completes in a day or two).
I really wish the xid was 64 bits instead of 32, but that's another topic
entirely.
