Don't generate 'zero' typeids in the output from gen_cross_product.
Tom Lane <tgl@sss.pgh.pa.us>
Don't generate 'zero' typeids in the output from gen_cross_product. This is no longer necessary or appropriate since we don't use zero typeid as a wildcard anymore, and it fixes a nasty performance problem with functions with many parameters. Per recent example from Reuven Lerner.
