Yeah. The "ESCAPE 'f'" part is OK. It's still the 123 that's of the wrong type. I'd say that message should point to 123 as well. Or to SIMILAR, if we take your stance that the error is with the SIMILAR TO operator in general. But pointing to ESCAPE is just weird. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
