There are some performance related patches, which I've applied at home
(should hopefully be uploading them later tonight).
As for serializing objects, there is a non-standard extension, but unless
your lo's are large then that shouldn't be affecting it.
There are examples in the source.

Subject: [INTERFACES] Performance issue with JDBC
Hi,
I am testing a Java application with the PostgreSQL JDBC that inserts
a bunch of
records into a database. Inserting 15 - 20 records every 10 seconds I
find that
the JDBC or Postgres can not keep up so I have a couple of questions.
1) Where can I get the latest and greatest code for the JDBC? I
downloaded the 7.0.2 PostgreSQL release and have been using the JDBC included
there. Have there been any patches since that may help performaance?
2) One of the fields inserted is a serialized Java object. I am saving
it as a large object right now because I could not figure out how to get anything
else to work. Could this be slowing things down? Is there a better way, such
as into a bytea or varchar? Also where might I find some sample code to
show me how to do it?
3) Any other performance tips that may help me?
Thanks,
Ken K
