Another thing that would be really nice would be to get rid of all the
warty special cases for SELECT INTO in executor/execMain.c. I have
thought about handling this stuff in a new tuple receiver type (cf
tcop/dest.h, dest.c) but haven't really pursued it. I also have some
old notes suggesting that we should merge this into INSERT/SELECT,
but that stuff has enough warts of its own that I'm not sure it's a
good path to pursue.
