[libpostgresql-jdbc-java] 06/09: When setNull is called with a TIME or TIMESTAMP type we cannot pass that type information on to the backend because we really don't know whether it is with or without a time zone. For a NULL value it doesn't matter, but we can't establish a type because a later call with a non-null value using the same PreparedStatement can potentially end up using a specific type that is incorrect.

    When setNull is called with a TIME or TIMESTAMP type we cannot pass
    that type information on to the backend because we really don't know
    whether it is with or without a time zone.  For a NULL value it
    doesn't matter, but we can't establish a type because a later call
    with a non-null value using the same PreparedStatement can
    potentially end up using a specific type that is incorrect.
