PPEM allows viewing and editing parameters of the DBMS instance.

The ALTER SYSTEM command is used to modify instance parameters. It modifies the postgresql.auto.conf file.

If an instance parameter was initially specified in the main configuration file, such as postgresql.conf, but later changed via PPEM and written to postgresql.auto.conf, the web application will display this parameter in both files. This behavior is expected, as values from postgresql.auto.conf take precedence over values specified in other configuration files.

PPEM reloads the configuration without restarting an instance when a restart is not required.
