Comment(by robe):

 doing a garden regress between 2.1.1 dev and 2.2.0 dev I see 2 key
 differences --

 all the ST_DumpPoints outputs for multitypes have changed to include SRID
 in, dump which is expected and desired.

 I'm also seeing a change in ST_ExteriorRing for curvepolygon.  That in
 2.1.1dev does not output the SRID but does in 2.2.  Is that expected by
 this change.  I would assume we'd want the same in 2.1.

 Output for this query
 {{{
 SELECT ST_AsEWKT(ST_ExteriorRing(foo1.the_geom)) As result
   FROM ((SELECT
 ST_GeomFromEWKT('SRID=4326;CURVEPOLYGON(CIRCULARSTRING(-71.0821 42.3036,
 -71.4821 42.3036, -71.7821 42.7036, -71.0821 42.7036, -71.0821
 42.3036),(-71.1821 42.4036, -71.3821 42.6036, -71.3821 42.4036, -71.1821
 42.4036) ) ') As the_geom)) As foo1 LIMIT 3;
 }}}

 2.2
 yields:


 {{{
 SRID=4326;CIRCULARSTRING(-71.0821 42.3036,-71.4821 42.3036,-71.7821
 42.7036,-71.0821 42.7036,-71.0821 42.3036)
 }}}

 But 2.1 yields


 {{{
 CIRCULARSTRING(-71.0821 42.3036,-71.4821 42.3036,-71.7821 42.7036,-71.0821
 42.7036,-71.0821 42.3036)
 }}}
