I didn't think it could be of any help. I have a copy of this database
on my local computer. I dump db on server and put it on local computer
every other day, so I thiink VACUUM is unneccessary here.
Anyway, I tried to VACUUM the db. No, the query didn't execute -
postgres ate all memory and died.
Any other idea, anyone?
