[postgis-users] add custom epsg

[Andy Colson]

2) I'm aware of the PostGIS tables but I'm pretty sure ogr2ogr isn't 
using them.

1) Sweet!  That's what I was looking for.  The proj was, obviousely, in 
proj format, not wkt, which is all I had.  But gdalsrsinfo was able to 
create a proj definition which I added to /usr/share/proj/epsg, and then 
it ran.

Thank you much.
