In which scenario would a system administrator need to edit the postgresql.conf file?

Editing the postgresql.conf file is essential for system administrators when they need to configure settings related to the PostgreSQL database that powers Qlik Sense. In this context, one of the most critical parameters within this configuration file is max_connections, which determines how many simultaneous connections can be made to the PostgreSQL database.

When a system administrator needs to handle an increase in demand for database connections—such as during peak usage times or after scaling the deployment—they will adjust the max_connections setting. This ensures that the system can handle the required number of concurrent users or applications without encountering connection errors.

Modifying other aspects of Qlik Sense, such as configuring proxy node settings, creating new users, or updating the Qlik Sense application, does not typically require changes to the postgresql.conf file, as these tasks involve different system configurations or user management processes.
