I didn't provide a patch --- I provided a proof-of-concept hack that
covered just two of the seventeen catalogs with OIDs (and not every case
even for those two). A real patch would likely be much more invasive
than this, anyway, because we'd want to fix things so that you couldn't
accidentally forget to use the free-OID-finding code.
