Alexey,

Can you put together a test case and I'll try to fix it?

I tried both driver from jdbc.postgresql.org (7.4 beta3) and from CVS (:pserver:anoncvs(at)anoncvs(dot)postgresql(dot)org:/projects/cvsroot) and discovered that with compatible=7.1 flag invoking rs.getBinaryStream() or rs.getBytes() on an OID column blocks forever (somewhere in java.net.SocketInputStream so I guess it's a server that is not responding). According to 7.4 documentation http://www.postgresql.org/docs/current/static/jdbc-binary-data.html, this should work. getBLOB() works great, but JBoss 3.2 server which I am using is only capable of dealing with large objects via getBinaryStream()/setBinaryStream().
