Thanks for the suggestion. I did not try it, though, because I already had three
solutions. The first and best was that data provider corrected the data. I still
continued a bit further and found that PostGIS 2.0 has a function
ST_FlipCoordinates for this purpose, and Spatialite has similar function
SwapCoordinates. I'd guess that it would be a bit harder to handle a list of
coordinates in linestrings and polygons.
