Not only do I have to agree with this statement, I feel it's important
to add a clarification regarding your original question.

Translating serial values submitted as 0 to something else is will
likely never be a PostgreSQL feature, as it is probably a violation of
the SQL standard. Databases are meant to store exactly what you submit,
barring any modifications by stored procedure or trigger.

If a database engine takes it upon itself to modify your data, it is no
longer a database, but an application that mimics one.
