Norbert, 

There is currently no mechanism to create linestrings from four 
columns, sorry.  If you can create a single column with the linestring
geometry in WKT format (ie.  LINESTRING(1 3,2 4)) then you could
read it from a flat table. 

I could add the capability you are requesting as a different case if you
need it badly enough.

Best regards,
