 - load your shapefile into postgis (shp2pgsql), assign an SRID to it,
corresponding to the shapefile's spatial reference system (SRS). (you
may find this site useful in order to help you determine your data's
SRS: http://spatialreference.org/)

- use the transform() function to reproject it to a Lat Long SRS, like
WGS84 for instance (SRID=4326)

- display the transformed data...
