It's not clear whether your type extends PGobject or implements SQLData.
Currently the PG driver only supports custom types via its own
non-standard method. You must extend PGobject and register it with the
driver's non-standard type map via either PGConnection.addDataType()
or via a URL paramater.

Yes, it would. I'll take a look.
