[postgis-users] Invalid SRID for geography type: ee4

[Philippe]

Thanks for the feedback regarding 4326.

I have data throughout the world and I then associate it with
administrative boundaries using shapefiles from various sources including
IGN France, IGN Belgium, OSM, etc...

I was under the impression that geometry was only to be used over small
areas. Am I wrong ? Should I really be using geometry and not geography ? I
usually use ST_covers and plane to use ST_intersection and ST_area

Thanks
