Hello PostgreSQL Community,

We are evaluating PostgreSQL 17 for enterprise use. Could you please confirm 
whether PostgreSQL provides built-in password policy enforcement without 
third-party extensions?

Specifically, we need to know whether PostgreSQL natively supports:
- Password complexity and minimum length
- Password expiration
- Password history and prevention of password reuse
- Account lockout after repeated failed login attempts

We are aware of the `passwordcheck` module. Does it provide these capabilities, 
or are additional extensions or external authentication systems required?

Thank you for your clarification.

Best Regards,

Mohammad Abuata
Senior Software Engineer
