badce86a2c First stage of reclaiming memory in executor by resetting short-term
memory contexts.  Currently, only leaks in expressions executed as
quals or projections are handled.  Clean up some old dead cruft in
executor while at it --- unused fields in state nodes, that sort of thing.

dd979f66be Redesign DISTINCT ON as discussed in pgsql-sql 1/25/00: syntax is now
SELECT DISTINCT ON (expr [, expr ...]) targetlist ...
and there is a check to make sure that the user didn't specify an ORDER BY
that's incompatible with the DISTINCT operation.
Reimplement nodeUnique and nodeGroup to use the proper datatype-specific
equality function for each column being compared --- they used to do
bitwise comparisons or convert the data to text strings and strcmp().
(To add insult to injury, they'd look up the conversion functions once
for each tuple...)  Parse/plan representation of DISTINCT is now a list
of SortClause nodes.
initdb forced by querytree change...

d03e98737c Replace typtoout() and gettypelem() with a single routine,
so that fetching an attribute value needs only one SearchSysCacheTuple call
instead of two redundant searches.  This speeds up a large SELECT by about
ten percent, and probably will help GROUP BY and SELECT DISTINCT too.
