Not only is the current behavior more logical (IMHO) and backward
compatible with existing Postgres application, it is consistent with the
SQL spec and most non-broken implementations of it. I think your chances
of getting the default behavior changed are slim indeed.

I think a more sensible proposal could be made for some sort of optional
"compatibility mode", as has been discussed many times in the past:
different NULL handling could theoretically be part of an Oracle SQL
