Right now the fact that attnum presents the logical order but not the
logical position is a problem for the JDBC driver. In the presence of
dropped columns there is no easy way to get from a pg_attribute entry to
logical position. I would hope that a new logical position column would
reflect the actual position and solve this problem.
