Anyone think it might be reasonable to add a GUC option that tells autovacuum to monitor for wraparound only, and not for more general usage based vacuuming? Something like autovac_wraparound_only. Not sure I like the idea, but thought it might be worth some discussion.

I believe 8.1 will actually stop allowing transactions if a wraparound is going to occur.
