[postgis-users] handling invalid geometry within a trigger

[LPlateAndy]

Hi,

I have a postgresql trigger function which creates a geometry from WKT
before data in inserted into the table. Saves on temp tables or on loading
and then updating.

Is there a way (possibly a plpgsql not postgis question) to ignore (treat as
NULL) a bum geometry - e.g a polygon with a single point

Andy
