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.

Change was actually made in a previous commit.

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

an ALTER TABLE ADD COLUMN command.  Per bug #896.

the table(s) modified by the original query would get checked for the
type of write permission needed by a rule query.

of the containing query (which really can only happen in a rule context).
Per example from Brandon Craig Rhodes.  Also, make the error message
more specific for the similar case with sub-select in FROM.  The revised
coding should be easier to adapt to SQL99's LATERAL(), when we get around
to supporting that.

from Greg Stark.  Also, twiddle the FuncCall case to not scribble on
the input structure, which was the proximate cause of the problem.
Someday we ought to fix things so that transformExpr() isn't called
on already-transformed trees ...

- Started with an Informix compatibility option.
