Hmm. The assertion (not shown above but you put in
parameterize_path:) seems to say that 'base relation for foreign
paths must be a RTE_RELATION' isn't right? But I don't see
anything putting such a restriction in reparameterize_path
itself. Could you tell me where such a restriction comes from? Or
who needs such a restriction? I think any assertions shouldn't be
anywhere other than where just before needed.
