Log message:
    ALTER TABLE DROP COLUMN works.  Patch by Christopher Kings-Lynne,
    code review by Tom Lane.  Remaining issues: functions that take or
    return tuple types are likely to break if one drops (or adds!)
    a column in the table defining the type.  Need to think about what
    to do here.

    Along the way: some code review for recent COPY changes; mark system
    columns attnotnull = true where appropriate, per discussion a month ago.
