Locating the database's system identifier

Each database server has a system identifier assigned when the database is initialized (created). The server identifier remains the same if the server is backed up, cloned, and so on.

Many actions on the server are keyed to the system identifier, and you may be asked to provide this information when you report a fault.

In this recipe, you will learn how to display the system identifier.

Getting ready

Connect as the postgres OS user, or another user with execute privileges on the server software.
