I would suggest starting with the 7.1 drivers off of
jdbc.postgresql.org. The functionality they provide for
Blobs/LargeObjects matches the documentation you are using.
You can also try the 7.2 drivers that you can also download from
jdbc.postgresql.org. In these drivers the implementation of getBytes()
and getBinaryStream() in ResultSet and setBytes()/setBinaryStream() in
PreparedStatement is different than is documented in the 7.1
documentation. These methods now work off of the bytea datatype for a
column instead of the oid datatype. However the getBlob()/setBlob() and
LargeObject API methods should all work the same as they did in 7.1.
