I guess you mean there's no BBOX in the GetCapabilities reply?. That's not
good. I think (but others may correct me) that there is a bug/hidden feature
in teh PostGIS connector of Mapserver that it does not get the extent of a
layer if one is not provided to it (as it would happen with eg. shape file
datasources).
It is anyway more efficient to provide the Extent in the .map file, so
Mapserver doesn't have to search for it. I also notice you are missing the
WEB METADAT that wms requires. So I would advice to put in the LAYER:
METADATA
"wms_title" "your title"
"wms_extent" "minx miny maxx maxy"
END
