Re: 8.2 Autovacuum BUG ? - Mailing list pgsql-performance

Hello all,

One more interesting observation made by me.

I have ran the below query(s) on production:

SELECT
    relname,
    age(relfrozenxid) as xid_age,
    pg_size_pretty(pg_table_size(oid)) as table_size
FROM pg_class
WHERE relkind = 'r' and pg_table_size(oid) > 1073741824
ORDER BY age(relfrozenxid) DESC ;
                    relname                                              |
xid_age | table_size
------------------------------------------------------------+---------+------------
