MapServer PostGIS connection: oids an gids to build a query

[Fabio D'Ovidio]

Hi !!

I have imported some geographical data (POINT) and their alphanumeric information in 
PostgreSQL\PostGIS database. The structure of the database is WITHOUT OIDS and there 
are no GIDs in the tables. So PK and FK are not numerical keys: they are string type keys!.

I have noticed that GeoServer (and uDIG Desktop side) is able to communicate with 
PostGIS without problem: i can display and query my vectorial layers.

MapServer (and QGIS Desktop side), instead, is able to connect and display vectorial data 
in PostGIS but it isn't able to query them. I am sure the problem is related to the absence of 
OIDS and\or GIDs. So MapServer is able only to query data if they have integer ids in 
PostGIS structure. WHY ??

How can I solve this problem ??

A  solution could be connect Geoserver to mapserver as a WMS layer, but I'd like to use 
ONLY MapServer!

Thanks a lot!
