[postgis-users] Error database geometry requires more points - postgis 1.5

[Mike Toews]

Hi Maria,

What version do you have?
SELECT PostGIS_Full_Version();

There are a few bugs for "geometry requires more points". How did you
ST_NumPoints() on a MultiLineString type? Is there a constraint for
the geometry type?
