Re: [webmaster] How to commit/vacuum a batch of delete statements in a postgresql function

Hi PostGresSQL Team

Could you advise us on how to commit records in a batch when one is doing batch wise deletion. I came across http://www.postgresql.org/message-id/60644bymua.fsf@dba2.int.libertyrms.com, but use of vacuum is giving an error as follows from function.
********** Error **********

ERROR: VACUUM cannot be executed from a function or multi-command string
SQL state: 25001

My stored procedure is of the format:

Loop 
  exit when <some condition> DELETE from incoming_table where xyz='123'; VACUUM incoming_table; -- or commit;
End Loop;

I thank you for the help.
