  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?
