Comment(by robe):

 Okay I stand corrected.  Evidentally you can get back a POINT EMPTY in
 gserialized if you use ST_AsText, but not if you use ST_AsEWKT.  There is
 a big disconnect there.

 Example:
 SELECT ST_AsText(ST_GeomFromText('POINT EMPTY'));
 -- gserialized
 POINT EMPTY

 -- out current install (not gserialized)
 MULTIPOINT EMPTY

 If you use ST_AsEWKT in both cases its

 MULTIPOINT EMPTY

 This AsEWKT/AsText mismatch in GSerialized may explain the large number of
 discrepancies I'm seeing between the two during my regress checks.
