This is wrong --- if you don't know what typmod to use, *always* pass -1
not 0. (I suspect that rettype is RECORD and that -1 would have
resulted in a NULL result.)
It seems like SPI is missing a needed function: it should have an
SPI_gettypmod to go along with SPI_gettypeid. This would probably
give you the correct typmod to pass to lookup_rowtype_tupdesc here.
