in the case where the node immediately above the scan is a Hash, Sort,
or Material node.  In these cases it's better to do the projection
so that we don't store unneeded columns in the hash/sort/materialize
table.  Per discussion a few days ago with Anagh Lal.

that turn into CASE expressions.  They evaluate their arguments at most
once.  Patch by Kris Jurka, review and (very light) editorializing by me.

a bad choice between sorted and hashed aggregation.

the outer query.  (The implementation is a bit klugy, but it would take
nontrivial restructuring to make it nicer, which this is probably not
worth.)  This avoids unnecessary sort steps in examples like
SELECT foo,count(*) FROM (SELECT ... ORDER BY foo,bar) sub GROUP BY foo
which means there is now a reasonable technique for controlling the
order of inputs to custom aggregates, even in the grouping case.

SIGPIPE disabled, and does not need to waste two syscalls per I/O on it.
