[Gdal-dev] problem with ogr2ogr -f PostgreSQL...

[Thom DeCarlo]

Ethan,
So... if I have a shapefile that uses a latlong/WGS84 projection whose EPSG
is 4326, then I use "shp2pgsql -s 4326 ...."?

Oh, goody.... another email list. I think that will make an even dozen. 

Thanks,
Thom

OBTW, Frank... did you see my comment that the postgresql driver
documentation page has a mistake in it?
