Hi! I want to buffer a road network in PostGIS, and dissolve the buffers on road names. I also want flat or square end caps. The ogr2ogr buffer tool offers dissolve but no end cap settings. The GRASS buffer offers a kind of square caps but no dissolve. The latter is necessary.
However, I see that the ogr2ogr buffer tool uses the PostGIS ST_Buffer function, whose syntax does allow for join, mitre and endcap settings. And the QGIS dialog offers a textbox for 'additional creation options'. But entering endcap=flat in that box does nothing, since the parameter is added to the end of a command string, and not within the brackets of the ST_buffer function. I need to know how to enter the endcap parameter properly. For now, I will let FME do the job at hand.
