The request for a "4.0 3.7 keygen password" seems to refer to a software activation key or a version number of a software product.

Requesting or using a keygen to bypass software licensing can be against the terms of service of the software and may violate copyright laws.
If you need the password for the program's PostgreSQL database for legitimate technical reasons, it is not readily available as it is unique to your system. However, there is a manual method using a tool called "Process Explorer" from Microsoft.

This should only be attempted by advanced users or IT professionals.
