a1627a1d64 From: David Hartwig <daybee@bellatlantic.net>
I have attached a patch to allow GROUP BY and/or ORDER BY function or
expressions.  Note worthy items:

1. The expression or function need not be in the target list.
Example:
            SELECT  name FROM foo GROUP BY lower(name);

2.   Simplified the grammar to use expressions only.

3.  Cleaned up earlier patch in this area to make use of existing
utility functions.

3.  Reduced some of the members in the SortGroupBy parse node.   The
original data members were redundant with the new expression node.
(MUST do a "make clean" now)

4.  Added a new parse node "JoinUsing".   The JOIN USING clause was
overloading this SortGroupBy structure.   With the afore mentioned
reduction of members, the two clauses lost all their commonality.

5.  A bug still exist where, if a function or expression is GROUPed BY,
and an aggregate function does not include a attribute from the
expression or function, the backend crashes.   (or something like
that)   The bug pre-dates this patch.    Example:

    SELECT lower(a) AS lowcase, count(b) FROM foo GROUP BY lowcase;
                 *** BOOM  ***

    --Also when not in target list
    SELECT  count(b) FROM foo GROUP BY lower(a);
                *** BOOM  AGAIN ***

So this should finally get cursors working. There was an ugly bug in it.

it is now only mergejoin.

7665e7b0a8 Allows the following query to succeed: "SELECT NULL ORDER BY 1;"
There are three or four cases in transformSortClause() and I had fixed
only one case for UNION. A second case is now fixed, in the same way; I
assigned INT4OID to the column type for the "won't actually happen"
sort. Didn't want to skip the code entirely, since the backend needs to
_try_ a sort to get the NULLs right. I'm not certain under what
circumstances the other cases are invoked and these are not yet
fixed up, though perhaps they don't need to be...

0668aa8817 Adrian Hall reported a problem to me that snprintf() doesn't exist in, at
least, Solaris 2.5.1.  We use it in backend/utils/adt/int8.c.

Add a check to configure so that we see if it exists or not, and, if not,
compile in snprintf.c from backend/port, which was taken from, and falls under
the same Berkeley license as us, the FreeBSD libc/stdio ...

As Bruce mentioned, this is due to the conflict among changes we made.
Included patches should fix the problem(I changed all MB to
MULTIBYTE). Please let me know if you have further problem.

P.S. I did not include pathces to configure and gram.c to save the
file size(configure.in and gram.y modified).
