Sorry for my ignorance, but I haven't been able to keep up lately --
what is the difference between pg_detoast_datum_packed and
pg_detoast_datum, and how do I know when to use each? E.g. I notice that
the related macro PG_GETARG_TEXT_PP is used in place of PG_GETARG_TEXT_P
in many (but not all) places in the backend.
Thanks,
Joe
