I'm not particularly on board with arguments like "we already broke a ton
of stuff so let's break some more".  Eventually you've managed to create
a daunting barrier to upgrading at all.

I think a more reasonable way to proceed is to install symlinks
pg_createuser -> createuser (or the other direction), mark the older names
as deprecated, and announce that we'll remove the old names a few releases
from now.  That gives people time to adjust.

Maybe we should handle createdb likewise, rather than just kicking it to
the curb.  I know I use it quite often; it's less typing than psql -c
'create database ...' postgres, and still would be with a pg_ prefix.
