We upgraded from postgres 7.4.5 to 8.2.5 a couple weekends ago.  I just
turned auto vacuum on today.

I manually inserted 4 entries in PG_AUTOVACUUM with enabled = 'f' to exclude
these larger tables

That we manually vacuum every night.  But the first tables that autovacuum
chooses to vacuum are

These 4 tables.  Am I missing something?


Another, possibly related question:  the 4 tables mentioned above are
vacuumed via a scheduled

Daemon that invokes the VACUUMDB shell.  But the LAST_VACUUM column in

Is not updated to reflect this vacuum.  Other tables vacuumed manually
during the day do have this

LAST_VACUUM column updated.  The autovacuum does populate the

For these tables.


Any insights?  Thanks
