Use one of the geometry constructors to create a geometry object
from the lat/lon with an appropriate SRID (e.g., 4326), then use
Transform() to convert the coordinates to another SRID.  Example:

test=> SELECT AsEWKT(Transform(GeomFromEWKT('SRID=4326;POINT(-118.2923 36.5785)'), 32611));
                       asewkt                       
----------------------------------------------------
 SRID=32611;POINT(384381.795377305 4048892.7545226)
(1 row)
