credcheck.password_valid_max not working as expected

[t-ushar]

Hi Team,

credcheck.password_valid_max seems not working as expected. Please find below the test result and let me know if I am doing anything wrong or hitting any bug?

VALID UNTIL should not be more than 180 days.

postgres=# show credcheck.password_valid_max;
 credcheck.password_valid_max 
------------------------------
 180
(1 row)

Created a user to test the situation and it went fine instead of failing

postgres=# create role credcheck_valid_max  with login password 'hfbeifDJHduiwqdfiwq18923&#%$' VALID UNTIL '2025-06-12';
CREATE ROLE
postgres=# alter user credcheck_valid_max VALID UNTIL '2025-06-12';
ALTER ROLE
postgres=# \dx credcheck

I can not reproduce with latest version 2.0.0:

contrib_regression=# SHOW credcheck.password_valid_max;
 credcheck.password_valid_max 
------------------------------
 180
(1 row)

contrib_regression=# create role credcheck_valid_max  with login password 'hfbeifDJHduiwqdfiwq18923&#%$' VALID UNTIL '2025-06-12';
ERROR:  require a VALID UNTIL option with a date beyond 180 days
