I am using spamassassin 3.2.0 and Postgresql 8.2.4 for bayes and awl. I am seeing several messages from Postgresql like the following
spamd[18408]: WARNING: nonstandard use of \\ in a string literal spamd[18408]: LINE 1: select put_tokens(1,'{"\\\\003\\\\272\\\\260\\\\274\\\\052"... spamd[18408]: ^ spamd[18408]: HINT: Use the escape string syntax for backslashes, e.g., E'\\'. In both /var/log/mail (where these are pasted from) and the postgresql logs.
