PPEM allows viewing and editing configuration parameters for all cluster nodes on a single page.

You can edit a parameter value for all nodes of the cluster or for a subset of nodes. If needed, it is possible to set different values for the same parameter on different nodes within a single operation.

If a 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 nodes when a restart is not required.

For information about viewing and editing parameters of a standalone instance, refer to Chapter 59.
