I agree. Its on the list on
http://lab.applinet.nl/postgresql-jdbc/#SQLException. This
requires new functionality in the backend.

Perhaps the SQLState string in SQLException can make this easier
(if we can support this with PostgreSQL). This is supposed to
contain a string identifying the exception, following the Open
Group SQLState conventions. I'm not sure how useful these are.
