There are many parts to a backend error message, see
http://www.postgresql.org/docs/8.0/static/protocol-error-fields.html
Putting all of these in the SQLException.getMessage() result would be
overload. The driver currently only puts in severity and message by
default, but will include more info based on the driver's loglevel. Is
position alone enough info to include? It really kind of depends on what
you are executing what info you want back. Position isn't relevent for
something like a duplicate key error. Also what if a function syntax
error isn't picked up until runtime? You'd also want "where". I can see
people also wanting detail and hint for certain messages. I see where
you're coming from, but I'm unsure what should really go into an error
message.
