I left that for future work, but I'm happy to have that in 9.6.  Thanks  
for improving and committing the patch!

One thing I'd like to discuss is GetUserMappingById/GetUserMappingId.  
Though those functions aren't used in any places, I didn't take them  
out, because I thought somebody else would need them someday.  But  
considering that user mapping OIDs now aren't available in RelOptInfos,  
at least the former might be rather useless.  Should we keep them in core?
