[gdal-dev] SQLite: create layer with wkbNone

[Even Rouault]

Martin,

Add the "-oo LIST_ALL_TABLES=YES" open option to your ogrinfo call: 
https://gdal.org/en/latest/drivers/vector/sqlite.html

(GPKG has a gpkg_contents table where non-spatial layers that are user 
facing are listed. There is no such thing in "pure" SQLite, and 
historically the driver has chosen to only list the ones registered in 
the geometry_columns table)
