    We have an application using the jdbc driver from postgres
    7.0.x, compiled under java1. We have migrated the database
    to 7.1.2, and would like to update the jdbc driver to match.

    The application selects() a timestamp as a date, which
    works fine under the earlier JDBC, and other databases such
    as MS SQLserver, but fails with a NumberFormatException under
    the new driver.

    Can anyone confirm if this is correct JDBC behaviour (in which
    case I have to persuade our developers to update their code :)

    Sample code appended.

    Thanks
