All of the above is a non-issue - it was implemented by tom in the parser,
and my code was removed. Howver, add primary key needs a regression test.

I still want to do the above - however Stephen Sazbo has ideas about
changing all the fk stuff...

Committed - it needs a regression test tho.

I'll dredge this up again if I can. All it does is add a standards
compliant alternative syntax for dropping those constraints. Tom - can you
just do this in the parser, like you did it for the ADD constraints???

And also depends on future fk changes.

Correct.

The above would be a nice feature...

Pretty clear.
