credcheck v4.5 has been released

Casablanca, Morocco - Febuary 05, 2026

PostgreSQL credcheck extension<= /h2>

The credcheck PostgreSQL extension provides= few general credential checks, which will be evaluated during the user cre= ation, during the password change and user renaming. By using this extensio= n, we can define a set of rules:

  • allow a specifi= c set of credentials
  • reject a certai= n type of credentials
  • deny password t= hat can be easily cracked
  • enforce use of = an expiration date with a minimum of day for a password
  • define a passwo= rd reuse policy
  • define the numb= er of authentication failure allowed before a user is banned
  • define a delay = on authentication failures
  • force users to = change their password after first login
  • throw a warning= N days before when the password user is about to expire

Release 4.5 has been published, it fixes se= veral issues reported by users since last release.

  • Fix error canno= t change data type of view column "roleid" from oid to regrole.
  • Add missing upg= rade SQL file from 4.3 to 4.4.
  • Fix error when = the user want to modify his password and credcheck.password_valid_until option is set. As we modify the VALID UNTIL clause it will generate an error message when the user changes his password: Only roles with the CREATEROLE attribute and the ADMIN option on role "..." may alter this role.
  • Set the tzp arg= ument in timestamp2tm() call to apply timezone to converted timestamp.

Upgrade require a PostgreSQL restart to rel= oad the credcheck library.

Complete list of changes and acknowledgemen= ts are available here<= /p>
