 SQLite links are processed by OGR interface, PostGIS by native GRASS-
 PostGIS interface. You can try to enforce OGR interface also for PostGIS
 links by `GRASS_VECTOR_OGR` environmental variable. Then `v.rast.stats`
 should work.

 GRASS_VECTOR_OGR=1 v.what.rast map=points_pg raster=rand column=morphology

 > For discussion see: https://lists.osgeo.org/pipermail/grass-

 Should be fixed in r70330 (trunk). Could you confirm?
