Обсуждение: renaming domain constraint

Here is a patch for being able to rename constraints of domains.  It
goes on top of the previously committed patch for renaming table
constraints.

I don't like the way you've modified get_constraint_oid(), which is
currently parallel to many other get_whatever_oid() functions and with
this patch, would no longer be.  There seems to be little point in
shoehorning the new functionality into the existing function anyway,
considering that you've conditionalized basically every piece of logic
in the function.  I think you should just invent a completely separate
function and be done with it.

get_relation_constraint_oid() plus get_domain_constraint_oid()?

Makes sense.  Updated patch attached.
