rearrangement of code that handles targetlist sorting.  Add a regression
test to catch future breakage.

patches of 9-Dec (permissions fix) and 13-Dec (performance) as well as
a partial fix for locking issues: concurrent DROP COLUMN should not
create trouble anymore.  But concurrent DROP TABLE is still a risk, and
there is no protection at all against creating a column of a domain while
we are altering the domain.
