Thanks Daniel,
but
Nope, tried and failed :-(

Maybe it has something to do with the way I created the table:

CREATE TABLE testpoints
(
   waarnemer character varying(40),
   plaats character varying(40),
   soort character varying(40),
   aantal integer,
   aantal2 character varying(40),
   opmerking character varying(200),
   the_geom geometry,
   CONSTRAINT testpoints_pkey PRIMARY KEY (oid),
   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) = 28992)
)
WITH OIDS;
ALTER TABLE testpoints OWNER TO postgres;

I wanted to have a table in which I had an auto incrementing id-column. 
This was the way to do that (according to mr Google :-) )

If I look at the table with pgAdmin III there is a column 'oid' with the 
id's in it. If I look with QGIS there is a column 'id'...

But if I do:
SELECT
	a.attnum,
	a.attname AS field,
	t.typname AS type,
	a.attlen AS length,
	a.atttypmod AS lengthvar,
	a.attnotnull AS notnull
FROM
	pg_class c,
	pg_attribute a,
	pg_type t
WHERE
	c.relname = 'testpoints'
	and a.attnum > 0
	and a.attrelid = c.oid
	and a.atttypid = t.oid
ORDER BY a.attnum

I don't see the oid column either....

It probably has something to do with the special meaning of an oid 
column in postgresql???

I will try to update my mapserver to the newest version (working with 
4.8.3 now...) and see if that works.
Other solution: add my own id's of use a sequence instead of this 
autoincrementing... Any postgresql guru's around?


Thanks, Richard
