Change typreceive function API so that receive functions get the same
optional arguments as text input functions, ie, typioparam OID andatttypmod. Make all the datatypes that use typmod enforce it the sameway in typreceive as they do in typinput. This fixes a problem withfailure to enforce length restrictions during COPY FROM BINARY.
