When using a junkfilter, the output tuple should NOT be stored back into
Tom Lane <tgl@sss.pgh.pa.us>
When using a junkfilter, the output tuple should NOT be stored back into the same tuple slot that the raw tuple came from, because that slot has the wrong tuple descriptor. Store it into its own slot with the correct descriptor, instead. This repairs problems with SPI functions seeing inappropriate tuple descriptors --- for example, plpgsql code failing to cope with SELECT FOR UPDATE.
