Thanks Regina and Strk for your ideas.
Yes, the single-sided buffers would probably solve my problem.
Any predictions on why this patch will make it into the Postgis trunk? I
assume it won't be possible for Postgis 1.4.0, but maybe for 1.4.1?

the actual diameter of the waste-water pipes (canalization). The linecaps
shouldn't be stroked, but the parallel offset
