 {{{
 SELECT ST_GeomFromText('CIRCULARSTRING( -1 0, 0 0, -1 0)'),
 (SELECT ST_CurveToLine(ST_GeomFromText('CIRCULARSTRING( -1 0, 0 0, -1
 0)'))),
 (SELECT ST_GeomFromText('CIRCULARSTRING(0 0, 4 0, 4 4, 0 4, 0 0)')),
 (SELECT ST_CurveToLine(ST_GeomFromText('CIRCULARSTRING(0 0, 4 0, 4 4, 0 4,
 0 0)')));
 }}}


 The second statement returns a line with half a radius of original
 circularstring.
