bot_factoid module fails under postgres 8.x

postgres doesn't understand "INSERT INTO {table} SET field=value......
postgres doesn't like the 'SET' part

the simple fix is removing this:
db_query("INSERT INTO {bot_factoid} SET subject = '%s', is_are = '%s', statement = '%s'", $subject, $is_are, $statement);

and replacing it with this:
db_query("INSERT INTO {bot_factoid} (subject, is_are, statement) VALUES ('%s','%s', '%s')", $subject, $is_are, $statement);

attached is patch.
