That would be really slick, especially given the fact that VACUUM runs
much faster than VACUUM ANALYZE for a lot of PG users.  I could change
my daily maintenance scripts to do a VACUUM of everything, followed by
a VACUUM ANALYZE of the small tables, followed by a VACUUM ANALYZE
ESTIMATE (or whatever) of the large tables.

Even cooler would be the ability to set a table size threshold, so
that VACUUM ANALYZE would automatically choose the appropriate method
based on the table size.
