Re: [GENERAL] pgAdmin complains about vacuuming required after fresh 8.1 install

Bump

Does anyone have *any* thoughts on this? This seems to be a fairly
common problem. Does anybody have any good links that they can
provide to find an answer?

My current test is that I have a table where all the rows were purged,
and then new ones inserted using a specific job. pgAdmin reports 0
estimated rows and 46 counted rows and therefore displays the popup
saying a vacuum should be run. I see in the PostgreSQL log that
autovacuum is vacuuming this database regularly.

Is this simply because pgAdmin has tighter settings and autovacuum
hasn't actually done anything with this table yet?
