That may very well help, I did a grep last month of all the places where
the not implemented exception is as a way to work out what work could be
done (see
http://archives.postgresql.org/pgsql-jdbc/2011-02/msg00087.php). Though
I've only had a little time to look since, there were some features that
I thought just weren't possible with Postgres so perhaps it's worth
discussing what features can be supported and need developing and which
methods should be changed to throw the better exception.
One feature that I noticed that isn't implemented is named parameters on
prepared statements. From a cursory glance I believe that it is possible
to that with Postgres, but I note that it's never been implemented for
JDBC 2 and upwards. Unless someone tells me it's technically not
possible I'd be prepared to invest some time over the coming weeks to
add that feature.
