A little suplement to previous answer You can also automate GRANT process by creating a table called e.g. locked_users containing role name and revoke timestamp then make a function that will check the time passed since revoking permissions for each user and if it will by equal or higher than time given e.g. 24 hours it will run GRANT LOGIN on the role.

<lukasz.brodziak@gmail.com> Hi,
As far as I know there is no such parameter in PG. If you use PG as a database for your program you can implement the feature in the appplication by logging the failed logins in separate table(or the one holding application users and their passwords) and then disable login for the user if number of failures is bigger than specified value.
Another way is to create a function in postgresql which will check failed login count and if the attempts go bigger than specified number it will run a REVOKE on the user role thus disabling login. Then admin will have to run GRANT for the user manually.

<fcavalie@us.ibm.com>Hi,
I've been searching the web and reviewing documentation, but I cannot find any reference to whether or not a parameter, for example, failed_login_attempts, exists in PostgreSQL that determines the number of attempts a user can make before being locked. In addition, if such a parameter or similar setup exists, is there also some database object that provides a current count of the failed login attempts?
Thanks,
Frank
