Yes, just a rename operation.

For the date range:

pgcvs log -d'2003-02-15 00:00:00 GMT<2003-02-18 00:00:00 GMT' -rHEAD

I see:

/src/include/optimizer/pathnode.h

tgl
Teach planner how to propagate pathkeys from sub-SELECTs in FROM up to
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.

/src/test/regress/expected/case.out

tgl
COALESCE() and NULLIF() are now first-class expressions, not macros
that turn into CASE expressions. They evaluate their arguments at most
once. Patch by Kris Jurka, review and (very light) editorializing by
me.

momjian
Remove IN/EXISTS TODO.detail item.
