This is coming from PostGIS:

postgis/gserialized_estimate.c:
/* If there's no useful features, we can't work out stats */
         if ( ! notnull_cnt )
         {
                 elog(NOTICE, "no non-null/empty features, unable to
compute statistics");
                 stats->stats_valid = false;
                 return;
         }



You might find more information from here:

Though FYI PostGIS 2.2.7 is past EOL:
