 > The '':text entry first gets passed into the text parsing routines which
 is where the failure actually occurs, not in st_isvalid. We have had
 internal arguments many times about where validity checking should occur,
 and the current situation is that trivially invalid geometries (1-point
 lines, unclosed polygons) are failed during parsing.

 Should shp2pgsql be allowed to insert trivially invalid geometries?
