Driver compatibility with 7.3 server

Hi everyone, happy holidays!  We are are currently using Postgresql 7.3
and would like to be able to use cursors for large selects (ie: using
Statement.setFetchSize()).  Unfortunately, this is not implemented in
the 7.3 JDBC driver.  Is it possible to use a newer version of the JDBC
driver, say 7.4, with the 7.3 version of the db server?  Thanks.
