pgsql: Flip the default typispreferred setting from true to false.

-----------
Flip the default typispreferred setting from true to false.  This affects
only type categories in which the previous coding made *every* type
preferred; so there is no change in effective behavior, because the function
resolution rules only do something different when faced with a choice
between preferred and non-preferred types in the same category.  It just
seems safer and less surprising to have CREATE TYPE default to non-preferred
status ...

This whole area makes a lot more sense now.

It was so difficult to explain before...
