I want to be able to change all field names to lower case from a data source when loading them in QGIS (SHP in particular).
Is it possible? Via the GUI, via Python.
Is it possible to convert field names to lower case when saving a layer with the "Save as" dialog?
Why? I regularly go back and forth between GIS files from OpenData portals and databases like PostGIS or Spatialite. Doing queries with upper case fields require quoting in these database and I want ease the pain. I would like to convert all my SHP field names to lower case.
