Log message:
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.

Was this responsible for an occasional

No, I don't think that's related. Can you provide a reproducible
example?

I've been seeing these regularly when compiling with GCC 3.0-to-be
snapshots with full optimization. The notices came in the regression test
at various places, always during update. Today, they're gone, with the
same compiler as yesterday.

Ugh. That sounds like a memory clobber to me --- and no, I don't
believe that my changes yesterday fixed it.
