I don't see that any of the proposed features would be very useful for answering the question "is my VM incorrect". Maybe they would fix problems, and maybe not, but in any case you couldn't rely on VACUUM to tell you about a problem. (Even if you've got warning messages in there, they might disappear into the postmaster log during an auto-vacuum. Warning messages in VACUUM are not a good debugging technology.) regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
