When I get a deadlock on psql, I get:

ERROR: deadlock detected
DETAIL: Process 12189 waits for ShareLock on transaction 3657282;
blocked by process 12109.
Process 12109 waits for ShareLock on transaction 3657280; blocked by
process 12189.

So my quesion is where did that detail information go in the jdbc driver?

I'm using postgres 7.4.7 with the jdbc driver that comes with it.
