[Proj] Projection conversion problem

[Damian Rakowski]

Thank you for your reply. That's true i can convert it using scripts, 
but I was thinking about different use case. I had a hope that thanks to 
proj integration in postgis I could define new coordinate system with 
proper proj configuration string (similar to this one: 
http://spatialreference.org/ref/epsg/4326/postgis/), and use such 
encoded coordinates directly in postgis.

Best Regards,

Damian
