[postgis-users] add custom epsg

[Andy Colson]

I know this isn't directly a postgis question, I'm kinda hoping someone 
will know anyway.

I'm trying to import a File.gdb into postgis, but the projection its in 
seems to be unknown.

I'm using ogr2ogr to do the conversion (and all my scripts are already 
setup to use it, so I'd rather not change to shp2pgsql), and I'm getting 
this error:

ERROR 6: EPSG PCS/GCS code 103782 not found in EPSG support files.  Is 
this a valid EPSG coordinate system?

The data is for Steele MN, and this does seem to be a thing:

http://edndoc.esri.com/arcims/9.2/elements/pcs.htm#103782

so how can I get ogr2ogr (ogrinfo, testepsg, etc) to use it?

Thanks for your time,

-Andy
