[gdal-dev] GDAL does not support gpkg files generated by GeoServer

[Raymond Nijssen]

Some fields in geopackages generated by GeoServer are not supported by 
GDAL. I have already made a ticket for GeoServer, but I'm unsure where 
the problem lies.

More info in the GeoServer ticket here:
https://osgeo-org.atlassian.net/browse/GEOS-11292

Gpkg output can contain fields of type INT4, VARCHAR(255) and FLOAT8 
which are not supported by GDAL/OGR. For this reason, QGIS, GRASS and 
FME ignore those fields on import.

The INT4 fields are visible as INT, but all other other fields are 
ignored. (There’s also an “unrecognized user version“.)

This also affects QGIS, GRASS and FME, cause they use GDAL for opening 
the data source.

Who's right and who's wrong here? :)

Kind regards,
