We've gotten requests like this at times for phppgadmin, and I think our
standard mantra has evolved into "re-implementing core database features in
the gui client tends to cause nasty surprises for our users". We actually
have some experience with this, since we used to implement alter table drop
column before it lived in postgresql, and we often had users complaining of
the limitations it had and the things that broke when they used it.
Looking at the OP's problem, the basic idea would be to create a new table and
then do some renaming hackery, adding the new column while pulling
information from the old table, but you run into all sorts of problems with
dependent objects when you do it that way. *shrug* Thats not news to people
who have studied it, thoough most people don't seem to grasp what is going on
in the system as a whole.

I'm not sure it is entirely inappropriate to discuss some of these items
on -hackers, if we're talking about general solutions to admin and/or gui
interfaceing problems (even the hacky non-core style solutions might be ok if
they are approach from the idea of being able to solve a problem at the sql
level)
