 This works:
 {{{
 select ST_CurveToLine('COMPOUNDCURVE((0 0, 10 0),CIRCULARSTRING(10 0, 20
 1, 30 10))');
 }}}

 This complains:
 {{{
 select ST_CurveToLine(st_multi('COMPOUNDCURVE((0 0, 10
 0),CIRCULARSTRING(10 0, 20 1, 30 10))'));
 ERROR:  Unsupported geometry of type CompoundCurve found in MultiCurve.
 }}}

 Weird to see it, given the non-multi one works fine...

 2.0.3 is affected. In 1.5 a COMPOUNDCURVE within a MULTICURVE is actually
 considered invalid at WKT parsing time, but this was fixed in 2.0 (I
 believe it's completely valid, COMPOUNDCURVE being a subclass of a CURVE
 exactly like LINESTRING and CIRCULARSTRING)
