Just running into it when upgrading Ubuntu from 12.04 (postgresql 9.1) to 14.04 (postgresql 9.3).
A fix, at least when creating tables, must be proposed since postgresql forbid the restoration of a database if this schema error is there.
Maybe it could be an assertion when parsing the model that specified that required is necessary at this place.
