Actual value rather than symbol

[Jason FU]

If I've got to show the actual value to the point mentioned by the the_geom
column from the table below:

CREATE TABLE sounding.sdgonly_20050722point
(
  gid serial NOT NULL,
  recno int8,
  elevation float8,
  dataflags int8,
  dispx float8,
  dispy float8,
  size float8,
  angle float8,
  scale int8,
  keyword varchar,
  usernum int8,
  fcode varchar,
  datatype int4,
  descflags int8,
  themenum int8,
  indexkey varchar,
  superflags int8,
  sourceid varchar,
  the_geom geometry,
  CONSTRAINT sdgonly_20050722point_pkey PRIMARY KEY (gid),
  CONSTRAINT enforce_dims_the_geom CHECK (ndims(the_geom) = 2),
  CONSTRAINT enforce_geotype_the_geom CHECK (geometrytype(the_geom) =
'POINT'::text OR the_geom IS NULL),
  CONSTRAINT enforce_srid_the_geom CHECK (srid(the_geom) = -1)
)
WITH OIDS;

what do I do for the map file?

Thanks!
