Hi Felipe,
the ST_OffsetCurve patch needs some more work before getting
included in the core. One thing is a change in the interface
so that sign of distance expresses which side of the curve
you want, another is rewriting to use the new GEOS API, as
the old one was deprecated. Finally, regress testing should
be added.

For more informations, refer to:
http://trac.osgeo.org/postgis/ticket/413

I'll be glad to work on such cleanup and integration but It'll
take a few hours and although a few people expressed interest
in this feature noone came up with fundings.

Maybe this could be an opportunity to try some crowdfunding, for example
trough http://pledgebank.com or similar.
