DEBUG [http-8443-2] - Unable to translate SQLException with SQL state '42601', error code '0, will now try the fallback translator
42601 is a syntax error, although I think you ought to complain to somebody about the fact that your tools don't show you the actual server error message.
Postgre version on the server 8.1 on development 8.3
8.1 does not support multiple rows in a VALUES construct.
