It is, because we want there to be a way of converting a custom or tar
format archive back to text.  I think that probably works out for the
best anyway, since pg_restore is a sufficiently dangerous operation
that you want to be darn sure you're not doing it on the wrong
database.  dropdb also requires a database name, while createdb does
not, for similar reasons...
