RE: DROP CONSTRAINT (UNIQUE) preliminary support

> Christopher, where are we on this patch?

No-one commented on it. It's not a committable patch, it was basically to
get some feedback to see if I was going in the right direction.

Since then, I decided to complete the ADD CONSTRAINT stuff first. I've
_almost_ finished ADD UNIQUE and ADD PRIMARY. I'll probably submit a patch
for those in the next couple of days. After that I'll worry about DROP
CONSTRAINT again.
