      The matrix-postgres role in the playbook has been replaced with the com.devture.ansible.role.postgres role (https://github.com/devture/com.devture.ansible.role.postgres).
      The new role is pretty much the same, but uses differently named variables.

      The matrix-postgres-backup role in the playbook has been replaced with the com.devture.ansible.role.postgres_backup role (https://github.com/devture/com.devture.ansible.role.postgres_backup).
      The new role is pretty much the same, but uses differently named variables.

      Please change your configuration (vars.yml) to rename all `matrix_postgres`-prefixed variables (`matrix_postgres_*` -> `devture_postgres_*`).

      The following variables in your configuration need to be renamed: {{ vars | dict2items | selectattr('key', 'match', 'matrix_postgres_.*') | map (attribute='key') | join(', ') }}
