This is an intentional change, as the previous behavior is obviously
wrong. Try putting in a value that does not conform to numeric(14,2),
such as 42.7777. It doesn't get converted.
In some future version we might want to think about applying actual data
conversions in such contexts, but right now the tuple conversion code
just insists on exact datatype matches.
The reason for the behavioral change is that plpgsql, which formerly
had really crummy tuple conversion logic with a whole bunch of other
deficiencies besides this one, now shares the logic used by
