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:
