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.

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 ...

longer works -- IncrHeapAccessStat() didn't actually *do* anything anymore, so no reason to keep it around AFAICS. I also fixed a grammatical error in a comment. Neil Conway
