  • Complete these steps if you are upgrading a distributed environment configured with an embedded PostgreSQL database.

    1. Examine the files in the pgdata directory on the master host before you upgrade the replica hosts.

    2. Navigate to the PostgreSQL data folder on the master host at /var/vmware/vpostgres/current/pgdata/.

    3. Close any opened files in the pgdata directory and remove any files with a .swp suffix.

    4. Verify that all files in this directory have correct ownership: postgres:users.
