pg_autovacuum only knows about table activity that has taken place while
it's running.  Example:  Table A has an analyze threshold of 1000, if
you perform 999 updates on table A, then kill and restart pg_autovacuum,
you will have to perform another 1000 updates before pg_autovacuum
performs an ANALYZE.  This is a large limitation of the current
implementation.

I tried to fix this for 8.0, but my autovacuum improvements didn't make
the cut.
