I think this should come as an additional parameter to the existing
ST_Buffer() function. Will require GEOS-3.3.0 to work and some care
in order to retain PostGIS support for older versions of GEOS (with
which you wouldn't have such support).

I can implement, document and regress-test that within another 10 hours.
