Generally JDBC questions are best discussed on the
pgsql-jdbc@postgresql.org list. First make sure you are working with the
latest source code available from
http://gborg.postgresql.org/project/pgjdbc/projdisplay.php which as
Dave mentioned has implemented some of these methods already. As to
whether anything needs to be added to the server, that depends on your
implementation. The Blob/Clob positioning seems like it could be done
more efficiently on the server side. Also the server doesn't have a Ref
datatype, so you really can't implement get/setRef without it.
