Postrgres problems??

[Boris Kovalenko]

Hello!
	I use SpamAssassin 3.0.2 with FreeBSD 5.3-STABLE and PostgreSQL 8.0. I 
found in my PostgreSQL's log many messages like:

ERROR:  column "newest_token_age" is integer, but expression type: 
character varying
COMMAND:  UPDATE bayes_vars SET newest_token_age = $1
                     WHERE id = $2 AND newest_token_age < $3

ERROR:  operator does not exists: integer + character varying
COMMAND:  UPDATE bayes_token
          SET spam_count = spam_count + $1,
              atime = $2
        WHERE id = $3
          AND token = $4
          AND spam_count + $5 >= 0
So, I think something is wrong with prepared PostgreSQL statements. May 
be they should be rewritten. Or may be something wrong is with my 
configuration :) Any comments?

With respect,
        Boris
