That is unlikely, but without more details it is hard to say what you need
to do.

You can use the keyword default in insert statements to get a default value.

The impression I get is that you expect postgres to make a best guess when
presented with ambiguous data. That is a very dangerous thing to do. I would
much prefer ambiguous data be rejected so that I can make sure what I think
the value is, is the same as what the database thinks the value is.
