For what it is worth the manuals for this version are here:
http://www.postgresql.org/docs/manuals/archive.html
I do not see anything in the manual that shows ALTER TABLE being useful in this
situation. I am afraid 7.1 is before my time and at this point I cannot think
of a solution other than set the assigned_to value in bugs to NULL where
assigned_to=user_id. Sort of negates the point of a relationship between bugs
and users. Another option would be to create a 'dummy' user to
whom 'unassigned ' bugs would be referenced.
