Old description:

> SELECT ST_DumpPoints(ST_GeomFromText('POLYGON EMPTY',4326)) As result;

New description:

 SELECT ST_ExteriorRing(ST_GeomFromText('POLYGON EMPTY',4326)) As result;

 Which I think is the cause of ST_DumpPoints crashing as well

 SELECT ST_DumpPoints(ST_GeomFromText('POLYGON EMPTY',4326)) As result;

Comment(by robe):

 Maxime,
 I think ST_DumpPoints is breaking by virtue of the fact that
 ST_ExteriorRing is the real culprit and it uses that when it sees a
 polygon type.
