The other 2 features that made VACUUM much less painful for me was
vacuum_cost_delay (8.0?) and allowing concurrent GiST indexes (8.1?).
Before those features were in, VACUUM could choke even a very
lightly loaded moderately large database for arbitrarily long times.
I guess I'd still like some more convenient tuning of autovacuum (perhaps
specifying X mbps disk I/O); but I'd say vacuum fell off my pet-peeve list
around the 8.1 timeframe.
