meta data information returned for domains

Hi guys,

I'm hoping someone can give me some advice for handling postgres domains 
withing JDBCs metadata...

I'm using the JDBC database metadata facilities to get information about 
tables for the purposes of auto generating program code. This has all been 
working fine until I got to testing it on a database that uses domains as 
the datatypes for the columns.

I havn't had a chance to investigate it thoroughly yet, but it I'm getting a 
datatype code of 1111 when the columns datatype is a domain. , I don't know 
if this has any special meaning or not, but it doesn't correspond to any of 
the java.sql types that I was comparing it to, so for now my code is broken.

I had a look around for information on this but didn't come up with 
anything... (yet) so I'm hoping someone here could point me in the right 
direction. Most essentially, I'd like to know if there is a standard way to 
get the base datatype information as that is what I need for code 
generation.

regards
Iain
