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.
