Solution

Please perform the below steps on the Primary EPM server as root to upgrade and verify PostgreSQL 16:

 

  1. Verify the currently installed PostgreSQL packages:
    rpm -qa | grep postgresql

  2. Navigate to:
    cd $AVAYA_HOME/Support/PrereqCheckerInstaller/ExternalPackages/PostgreSQL

  3. Verify that PostgreSQL 16 RPMs are available:
    find . -type f | grep postgresql16

  4. Run the PostgreSQL 16 installation:
    ./Install_PostgreSQL.sh 16

  5. Verify the installed PostgreSQL packages:
    rpm -qa | grep postgresql

  6. For SP2, verify/update the symbolic link:
    ls -l /usr/bin/pg_isready

  7. Reboot the server to ensure all changes take effect. Reboot is mandatory.
    sync; reboot

  8. After the server comes back up, verify:
    postgres --version
    pg_isready --version
