Vaccum and analyze counters in pgstat

От

Attached is a patch that adds columns to pg_stat_*_tables for number
of [auto]vacuum and [auto]analyze runs on a table, completing the
current one that just had the last time these ran. It's particularly
useful to see how much autovac is doing on the tables, but I included
the counts of regular vacuum and analyze as well for completeness.

Comments?

Looks reasonably sane in a quick read-through.

"information about vacuum and analyze actions" might read better.

Likewise values -> actions here.

Applied with suggested documentation changes.
