[postgis-users] invoking inverse transforms

I'm trying to do an inverse lambert conformal conic- transforming a 
multipolygon of coordinates that are in state plane meters into a 
multipolygon of longitude and latitude coordinates.

I haven't been able to discern how to call an inverse transform() within 

Is there some way to do the equivalent of invproj?

Do I need to build my own special spatial_ref_sys entry?

Thanks for your input.
