[postgis-users] equal area projection

Hi all

I am trying to add a new equal area projection into postgis (behrmann and/or
Robinson). I am struggling to get this to work. From the "
spatialreference.org" website I uploaded the following into postgis:

 INSERT into spatial_ref_sys (srid, auth_name, auth_srid, proj4text, srtext)
values ( 954017, 'esri', 54017, '',

After this I add some data in Behrmann projection using shp2pgsql, but
trying a transform query such as

select AsText(transform(GeomFromText('Point(-75 10)',4326),954017))

does not work and crashes postgis.

I really need to get a global equal area projection to work for my project
(have been using Plate Carree, but obviosly not good for performing area
intersects) and would be grateful for any pointers on how to do this.

Many thanks
