Drawbacks of that approach are mainly you would need to specify a lot
of attributes for newly written functions to get the behaviour you
want, and it also won't reduce the complexity of the language, rather
the contrary, the more settings and the more alternative ways of doing
things, the more complex will the implementation of the language
become. This is why postgresql is surperiour to for instance mysql, as
with mysql you need to set a lot of obscure settings to get the
desired behaviour, like making 2014-03-31 an error instead of allow
the invalid value. I wish plpgsql was just like postgresql, a very
strict language.
