[#1]

Environment

• EDR Server: All Versions

Question

Can old versions of PostgreSQL be uninstalled after an EDR Server upgrade installs a new major version? Example:

Can postgres 10.17 be removed after the EDR Server 7.6.0 upgrade installs 13.4?

Answer

Yes, old versions of PostgreSQL are no longer needed by EDR Server and can be safely removed.

Additional Notes

• Review the Third Party Software Updates section of EDR Server Release Notes for potential upgrades to postgres.
• A yum remove command should be sufficient to uninstall old postgres versions. Example:

  yum remove postgresql10 postgresql10-libs postgresql10-server
