Hello, I asked this question on JDBC list, but it seems "dead". I found alternative JDBC driver marked as Beta 2 (actually last time bumped to Beta 2.1) http://softperience.eu/pages/cmn/ngpgjdbc.xhtml. We still test it. Those features are, mainly, in our interest - binary transfer - possibility of loading large bytea in JVM with small heap (we loaded about 1GB in JVM with 256MB) - XA But, I would like to ask, if someone of You have tested it, and / or compared. We actually looking for general opinion if it's suitable for JavaEE + JPA/Hibernate Regards, J. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
