I'm a little confused as to why the extent of EPSG:4326 is given as Douglas County in Wisconsin, in proj.db
https://github.com/OSGeo/PROJ/blob/master/data/sql/extent.sql#L3305 INSERT INTO "extent" VALUES('EPSG','4326','USA - Wisconsin - Douglas','United States (USA) - Wisconsin - Douglas county.',46.15,46.76,-92.3,-91.55,0); Best regards, Will Temperley
