Comment (by robe):

 Mark,

 Still not quite right.

 I can do this on PostgreSQL 8.4 now

 SELECt ST_Union(ARRAY[null,null,null,null]) and I correctly get null back.

 If I do
 select ST_Union(Array[ST_GeomFromText('POINT(1 2)'),null,null,null]);

 or
 SELECT ST_Union(the_geom)
 FROM (VALUES (ST_GeomFromText('POINT(1 2)') ), (null), (null) ) As
 foo(the_geom)

 I still get the same error of:

 ERROR:  Unknown geometry type: 0
