I would like to find the minimum, maximum and (weighted?) average value of the raster cells intersected by a line (vector) layer. This is similar to what common "Zonal Statistics" tools do, but they all work on polygons only, not lines.
It appears that Hawths Tools have something similar called Line Raster Statistics, but I'm looking for an Open Source (non esri) solution.
I use QGIS, so either a native solution, plugin, or SQLite or PostGIS solution would be preferred.

For calculating stats from raster cells intersected by line, you can use GRASS
v.rast.statsdirectly from QGIS processing toolbox. It can calculate 13 different stats.
