## PostgreSQL credcheck extension
The credcheck PostgreSQL extension provides few general credential checks,
which will be evaluated during the user creation, during the password change
and user renaming. By using this extension, we can define a set of rules:
* allow a specific set of credentials
* reject a certain type of credentials
* deny password that can be easily cracked
* enforce use of an expiration date with a minimum of day for a password
* define a password reuse policy
* define the number of authentication failure allowed before a user is banned
Release v2.1 adds a two new features and fix issues reported by users since
last release.
- Add custom configuration variable `credcheck.encrypted_password`
allowed to allow the use of encrypted password in CREATE or
ALTER ROLE statement. Default (off) is to not allow encrypted password
and to fire an error.
- Add the possibility to check the easiness of a password by the use of
the cracklib tool. This work is simply a integration of a copy/paste
from the passwordcheck extension available in the contrib/ directory.

- Fix failure count issue when ssl is disabled.
Upgrade require a PostgreSQL restart to reload the credcheck library.
