          @summary Verify if a connection can be successfully established

          Verify that a connection can be successfully established between a node
          and the PostgreSQL server.  Its primary use is as a precondition to
          prevent configuration changes from being applied if the PostgreSQL
          server cannot be reached, but it could potentially be used for other
          purposes such as monitoring.
