Tom Lane 38bb77a5d1 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.
