patch is applied:

	Rewrite rules on relation level work fine now.

	Event qualifications on insert/update/delete  rules  work
	fine now.

	I  added  the  new  keyword  OLD to reference the CURRENT
	tuple. CURRENT will be removed in 6.5.

	Update rules can  reference  NEW  and  OLD  in  the  rule
	qualification and the actions.

	Insert/update/delete rules on views can be established to
	let them behave like real tables.

	For  insert/update/delete  rules  multiple  actions   are
	supported  now.   The  actions  can also be surrounded by
	parantheses to make psql  happy.   Multiple  actions  are
	required if update to a view requires updates to multiple
	tables.

	Regular users  are  permitted  to  create/drop  rules  on
	tables     they     have     RULE     permissions     for
	(DefineQueryRewrite() is  now  able  to  get  around  the
	access  restrictions  on  pg_rewrite).  This enables view
	creation for regular users too. This  required  an  extra
	boolean  parameter  to  pg_parse_and_plan() that tells to
	set skipAcl on all rangetable entries  of  the  resulting
	queries.       There      is      a      new     function
	pg_exec_query_acl_override()  that  could  be   used   by
	backend utilities to use this facility.

	All rule actions (not only views) inherit the permissions
	of the event relations  owner.  Sample:  User  A  creates
	tables    T1    and    T2,   creates   rules   that   log
	INSERT/UPDATE/DELETE on T1 in T2 (like in the  regression
	tests  for rules I created) and grants ALL but RULE on T1
	to user B.  User B  can  now  fully  access  T1  and  the
	logging  happens  in  T2.  But user B cannot access T2 at
	all, only the rule actions can. And due to  missing  RULE
	permissions on T1, user B cannot disable logging.

	Rules  on  the  attribute  level are disabled (they don't
	work properly and since regular users are  now  permitted
	to create rules I decided to disable them).

	Rules  on  select  must have exactly one action that is a
	select (so select rules must be a view definition).

	UPDATE NEW/OLD rules  are  disabled  (still  broken,  but
	triggers can do it).

	There are two new system views (pg_rule and pg_view) that
	show the definition of the rules or views so the db admin
	can  see  what  the  users do. They use two new functions
	pg_get_ruledef() and pg_get_viewdef() that are  builtins.

	The functions pg_get_ruledef() and pg_get_viewdef() could
	be used to implement rule and view support in pg_dump.

	PostgreSQL is now the only database system I  know,  that
	has rewrite rules on the query level. All others (where I
	found a  rule  statement  at  all)  use  stored  database
	procedures  or  the  like  (triggers as we call them) for
	active rules (as some call them).

    Future of the rule system:

	The now disabled parts  of  the  rule  system  (attribute
	level,  multiple  actions on select and update new stuff)
	require a complete new rewrite handler from scratch.  The
	old one is too badly wired up.

	After  6.4  I'll  start to work on a new rewrite handler,
	that fully supports the attribute level  rules,  multiple
	actions on select and update new.  This will be available
	for 6.5 so we get full rewrite rule capabilities.

no longer returns buffer pointer, can be gotten from scan;
	descriptor; bootstrap can create multi-key indexes;
pg_procname index now is multi-key index; oidint2, oidint4, oidname
are gone (must be removed from regression tests); use System Cache
rather than sequential scan in many places; heap_modifytuple no
longer takes buffer parameter; remove unused buffer parameter in
a few other functions; oid8 is not index-able; remove some use of
single-character variable names; cleanup Buffer variables usage
and scan descriptor looping; cleaned up allocation and freeing of
tuples; 18k lines of diff;

Don't bother checking for alternate strategies if so
 since it was more likely a function or some other non-operator anyway.

 indices for restriction clauses containing a constant.
Note that if an index does not match directly (usually because the types
 on both side of the clause don't match), and if a binary-compatible index
 is identified, then the operator function will be replaced by a new
 one. Should not be a problem, but be sure that if types are listed as
 being binary compatible (in parse_coerce.h) then the comparison functions
 are also binary-compatible, giving equivalent results.

it is now only mergejoin.

1. Removes the unnecessary "#define AbcRegProcedure 123"'s from
pg_proc.h.

2. Changes those #defines to use the names already defined in
fmgr.h.

3. Forces the make of fmgr.h in backend/Makefile instead of having
it
   made as a dependency in access/common/Makefile  *hack*hack*hack*

4. Rearranged the #includes to a less helter-skelter arrangement,
also
    changing <file.h> to "file.h" to signify a non-system header.

5. Removed "pg_proc.h" from files where its only purpose was for
the
   #defines removed in item #1.

6. Added "fmgr.h" to each file changed for completeness sake.

Turns out that #6 was not necessary for some files because fmgr.h
was being included in a roundabout way SIX levels deep by the first
include.

"access/genam.h"
 ->"access/relscan.h"
   ->"utils/rel.h"
     ->"access/strat.h"
       ->"access/skey.h"
	 ->"fmgr.h"

So adding fmgr.h really didn't add anything to the compile, hopefully
just made it clearer to the programmer.

S Darren.

Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.

It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.

This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )

This patch is against the 6.3 sources, as it took a while to
complete.

Please review and apply,

Cheers,

yyerror ones from bison. It also includes a few 'enhancements' to
the C programming style (which are, of course, personal).

The other patch removes the compilation of backend/lib/qsort.c, as
qsort() is a standard function in stdlib.h and can be used any
where else (and it is). It was only used in
backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c,
and backend/storage/page/bufpage.c

There's more to come. Please review these patches. I ran the
regression tests and they only failed where this was expected
(random, geo, etc).
