I'm trying to help out the rails people. Currently they have

Why would this be nicer? What's the advantage? pg_dump in particular
*is* a client application. It isn't called from within another
connection. As loading a schema from a file via psql, that's also
fairly common practice. Alternatives to createdb or dropdb are just
as easily handled by passing a command to psql using its -c flag.
Another point to consider is that using CREATE/DROP DATABASE instead
of the createdb/dropdb client applications requires a database
connection: if you don't have a database to connect to, you can't use
them. Of course, you could initially connect to the postgres database
(or template1 in older version), but that could require configuring
parameters for another database in database.yml. What's the advantage?
