1. Can we lock or expire a ROLE / USER

   Subramanian,Ramachandran <ramachandran.subramanian@alte-leipziger.de> — 2025-09-19T08:32:33Z

   Hello all,
   
   
      Absolute novice in Postgresql, coming from the Mainframe world.  Kindly forgive my ignorance.
   
   Is it possible to LOCK or DEACTIVATE or EXPIRE a USER ( ROLE with LOGIN ) after
   
   
     1.  A set period of inactivity
     2.  5 Wrong password attempts
   
   I searched through the manals and did not find any mention of such a facility.
   
   If it is not possible at the database level, can this be implemented in any other way?
   
   
   Regards
   
   Ram

   Otherwise you’d want to log login events and you could then script a tool
   to alter role upon seeing relevant log activity.

   PostgreSQL doesn't offer support for these functionalities.
   It also does not allow you to enforce password complexity rules.

   The way to do that is to authenticat database users using a central identity
   management system like Kerberos.  See the documentation for a list of supported
   authentication methods:
   https://www.postgresql.org/docs/current/client-authentication.html

   Ram,
    
   For PostgreSQL to implement features outlined below would be re-inventing the wheel as much of this feature  functional already exist in Directory Service security systems like Active Directory/LDAP.  Plus there are lots of good reasons that these types of security features be centrally located and administered rather than devolved into individual database instances and servers.
    
   To get some of the functionality I would point you to to Open LDAP directory service https://en.wikipedia.org/wiki/OpenLDAP.  PostgreSQL provides client integration with LDAP see https://www.postgresql.org/docs/current/auth-ldap.html
   However I will point out the LDAP implementations, integration and administration can be quite complex.
