%ud in a printf format strings instead of just %u.

There were three occurances of this in catalog_utils.c,
two in parser.c and one in rewriteSupport.c in the oid
patch that I submitted and was applied.  They won't crash
anything, but the error messages will have a 'd' after the
Oid.  Annoying, but none are db-threatening.

Sorry about that folks...I'll be more careful in the future...
