 I needed some new functionality and found topic:
 http://postgis.refractions.net/pipermail/postgis-users/2009-
 June/023717.html

 In that topic there was link to:
 http://trac.osgeo.org/geos/ticket/215

 It was exactly what I was looking for so I added this to PostGIS.

 Example of use:
 {{{
 select st_astext(ST_Single_Sided_Buffer(
 ST_GeomFromText('LINESTRING(10 10,10 20, 20 20 )'),
 1,'join=mitre mitre_limit=5.0',0));
 --------------
 LINESTRING(20 19,11 19,11 10)

 select st_astext(ST_Single_Sided_Buffer(
 ST_GeomFromText('LINESTRING(10 10,10 20, 20 20 )'),
 1,'join=mitre mitre_limit=5.0',1));
 --------------
 LINESTRING(9 10,9 21,20 21)
 }}}
