Things have changed a bit (we're more closely following the SQL spec,
for one thing :).

I don't think it's actually required (per spec) for us to allow this,
but we do because it makes some sense.

To give 'testuser' the rights of 'testrole' you should do:
grant testrole to testuser;

This works for backwards compatibility, really, not because it's
something the 'ALTER ROLE' command is supposted to be able to do.

I had made this work in my original patch (iirc) but I believe Tom
dropped it because you really should be using GRANT instead.

Using the 'grant role statement', per the SQL spec.

This is because create role, alter role, alter user, etc, use the
same set of options (since there's a large overlap) in the syntax,
though some things don't make sense for some of those commands.
