Command tags in create/drop scripts

The messages output by the "scripts" always seemed unnecessary to me, e.g.,

$ createdb foo
CREATE DATABASE

A Unix program (hi Magnus) shouldn't need to say anything if the requested 
action succeeded.

I believe the history of this output is actually that these scripts simply 
used to call psql and no one really questioned why the output should be this 
way.  There are also some inconsistencies, e.g., createlang doesn't output 
anything, and createuser outputs CREATE ROLE.

I would just remove all this, but I suppose this will be controversial?
