Uninstalling Postgres Enterprise Manager components on Linux v8

The process of uninstalling the PEM server or Agent is platform-specific. The name of the package for PEM server is edb-pem-server and for PEM Agent is edb-pem-agent.

If you uninstall the PEM server package from a host, the PEM Agent package installed on the same host doesn't get uninstalled. But if you uninstall the PEM Agent package, then the PEM server package installed on the same host also gets uninstalled.

Note

Before uninstalling the PEM Agent, you need to de-register the agent first. You can de-register the agent using the pemworker command-line utility. After that, you can proceed with the uninstallation steps.

Uninstalling PEM components from RHEL or Rocky Linux or AlmaLinux hosts

You can use variations of the rpm command to remove the installed packages from Rocky Linux/AlmaLinux/RHEL 8.x hosts. Also, you can use the dnf remove command to remove the installed package from Rocky Linux/AlmaLinux/RHEL 8.x hosts. Note that removing a package does not damage the PEM data directory.

  • Include the -e option when invoking the rpm command to remove an installed package; the command syntax is:

    rpm -e package_name

Where package_name is the name of the package that you would like to remove.

  • You can use dnf remove command to remove the pem server or Agent along with the edb-pem and edb-pem-docs dependencies on Rocky Linux or AlmaLinux or RHEL 8.x hosts. To remove a package, open a terminal window, assume superuser privileges, and enter the command:

    dnf remove package_name
