I think I see what you mean: reocrds obtained from a RDBMS won't carry a
unique shape_id the same way as shapefiles and other file-based formats
will.  So you don't have any shape_id to pass to getShape() after a
query.  I don't know about SDE and PostGIS, but I have used SDO before
(outside of the MapServer world) and I believe that there is nothing in
OracleSpatial that can easily be mapped to a shape_id.

I guess the best ones to answer this question are the developers of the
SDO, SDE, and/or PostGIS connections:  Do the database-based connections
in MapServer have any equivalent of a shape_id?  If not then what should
one do to retrieve the shapes returned by a queryByPoint() in MapScript
for instance?
