0fc13f582a Make sure resdomno for update/insert match attribute number for 
rewrite system.  Restructure parse_target to make it easier to
understand.

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 ***

7b6cbd53f7 func_error() changed so that if caller is passed with NULL value, its 
output at least doesn't appear that its missing something.

wasn't particularly confident with removing 'caller' altogether :(

7439ba64b1 Use "Oid" type where applicable and %ud instead of %d. Thanks Darren King. 1996-12-11 03:18:12 +00:00
Bruce Momjian
63df35e249 This patch changes quite a few instances of references of Oid's 
as ints and longs.  Touches on quite a few function args as
well.  Most other files look ok as far as Oids go...still checking
though...

Since Oids are type'd as unsigned ints, they should prolly be used
with the %ud format string in elog and sprintf messages.  Not sure
what kind of strangeness that could produce.
