[postgis-users] srid

I am attempting to learn Postgis to use as a geometric tool rather than a 
geographic tool.

The function ST_Transform(geometry, integer)  seems to be potentially quite 

Apparently, the integer required is the new coordinates referenced by the 
srid. Is there some way of building a spatail reference table in which I can 
enter my coordinates that the ST_Transform function will recognize. My first 
simplistic attempt (entering a coordinate with an id) didn't work.
