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.

The <literal>DROP COLUMN</literal> command does not physically remove
the column, but simply makes it invisible to SQL operations. Subsequent
inserts and updates of the table will store a NULL for the column.
Thus, dropping a column is quick but it will not immediately reduce the
on-disk size of your table, as the space occupied
by the dropped column is not reclaimed. The space will be
reclaimed over time as existing rows are updated.
To reclaim the space at once, do a dummy <command>UPDATE</> of all rows
