pgAdmin 4 has a selection of configuration options (Preferences) that you can use to customize your pgAdmin client. To open the Preferences dialog, select Preferences from the File menu.
The left pane of the Preferences dialog displays a tree control; each node of the tree control provides access to options that are related to the selected node.
Expand the Browser node of the tree control to personalize your workspace.
Use the options on the Display dialog to specify general display preferences:
Move the Show system objects switch to the True position to display system objects in the pgAdmin tree control. This option instructs pgAdmin to display objects such as system schemas (e.g. pg_temp*) and system columns (e.g. xmin, ctid) in the tree control.
Use the options on the Nodes dialog to select the object types that will be displayed in the pgAdmin tree control.
