Hi. I've just discovered the check_postgres utility and am running
all the tests against my database.
The "last_analyze" test comes out critical - many tables unanalyzed
for 8 weeks.
I am running PostgreSQL 8.4.4 with default autovacuum settings. I
thought autovacuum was
supposed to take care of running vacuum and analyze.
Per "last_analyze", 9 out of my 100 tables have been analyzed within
the last 24 hours.
Why aren't all my tables being analyzed? How do I troubleshoot this, please?
Best,

P.S. I checked the PostgreSQL logs, and in the last week, I just have
three messages with "vacuum" in them:
