Обсуждение: BYTEA dump compatibility

Hi all,
I have a database populated with jdbc7.2dev on postgres 7.1. I have used
BYTEA fields to store serialized java object.
I have to transport the existing data from version 7.1 to version 7.3.1.
The dump and import procedure runs well, but if I try to read the BYTEA
on new db (7.3.1) with new JDBC Driver, my deserialize procedure throws
an error (InputStream does not contain a serialized object).
I have used setBynaryStream and getBynaryStream to write and read
object.
If I use the old JDBC Driver (jdbc7.2dev) on new postgres (7.3.1) then
all runs well.

Is there a BUG in new jdbc driver?

Thanks in advance at all.

Pier Paolo.
