Comment (by robe):

 Another instance ST_DumpSegments should either say it doesn't work with
 compound curves, or do something useful



 {{{
 SELECT dp.path, ST_AsText(dp.geom)
 FROM ST_DumpSegments('COMPOUNDCURVE(
 (2 2, 2.5 2.5),
 CIRCULARSTRING(2.5 2.5, 4.5 2.5, 3.5 3.5),
 (3.5 3.5, 2.5 4.5, 3 5)
 )'::geometry) AS dp;

 path | st_astext
 ------+-----------
 (0 rows)

 }}}

 Doesn't give an error but returns no rows.
