6.3.1. Using Control Center
Control Center uses menus, icons, and table displays to make it easy for you to create and manage PostgreSQL database services and clusters.
Along the top of the main program window is the Menu Bar. The Menu Bar enables you to create and manage database clusters, control database engine state, edit configuration files, and manage preferences, among other things.
Below the Menu Bar is the Toolbar. The Toolbar enables you to create clusters, start/stop/restart database engines, refresh the displayed information, and hide or show the Detail Area.
Below the Toolbar is the Summary Area. The Summary Area displays the clusters defined on the current server as well as displaying the current state of the clusters.
Below the Summary Area is the Detail Area. The Detail Area displays various information about the selected cluster.
Below the Detail Area is the Status Bar. The Status Bar displays the current state of Control Center as well as the server's name and IP address.

|---|---|
Control Center executes only one operation at a time—all commands are disabled while a command is being performed. |
