As I use a PostGIS source with geometry type linestring, it is important that the new geometry is still linestring and not multilinestring type. "Merge selected features" tool and "JOIN" in QAD-Plugin both create multilinestrings. Has anyone an idea how to directly merge into linestring or how to change geometry type after merging? Thanks for your suggestions!
I'm not sure I completely understand what you want but you could run
multipart to singleparts from the Vector/Geometry Tools menu on the
multilinestring layer to generate a layer with just linestrings.
