[postgis-users] NOTICE: no non-null/empty features, unable to compute statistics

[Jason Mathis]

I am stumped on it. I think i remember seeing something like this before, but can’t quite recall.  

Queries both return zero. 

'POSTGIS="2.1.3 r12547" GEOS="3.4.2-CAPI-1.8.2 r3921" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.9.2, released 2012/10/08" LIBXML="2.7.6" LIBJSON="UNKNOWN" RASTER'

i even tried putting a bogus null row in there but I still got the message. 

thanks!

It means it sampled 30000 rows and didn't find any geometries that
were non-null or non-empty. I suppose it could mean a bug, though that
code's been around for a while.

select count(*) from yourtable where geom is null;
select count(*) from yourtable where st_isempty(geom);
select postgis_full_version();
