(Mark or Bruce?) It fixes a problem when cpp gives a warning when
precompiling /dev/null like: "/dev/null", line 1: 1506-229 (W)
File is empty. This leads to a hangup when doing the description
load during initdb, since stderr also ends up in the global1.description

Support SERIAL column type. Expand column marked is_sequence into three
statements:
- the table definition with a default clause referencing the sequence;
- a CREATE SEQUENCE statement;
- a UNIQUE constraint, which expands into a CREATE INDEX statement.
This is not a perfect solution, since the sequence will remain even if
the table is dropped. Also, there is no absolute protection on updating
the sequence column.
Move debugging printout of the query tree to print for all cases.
Formerly came just after early exit from loop for command nodes,

I have found a minor problem with current configure.in.
[AC_MSG_RESULT(yes) AC_DEFINE(HAVE_LONG_INT_64)],
this line produces something like:
echo "$ac_t""yes" 1>&6 cat >> confdefs.h <<\EOF
and would append garbage "yes cat" to confdefs.h. Of course the
result confdefs.h is not syntactically correct therefore following
tests using confdefs.h would all fail. To avoid the problem, we
could switch the order of AC_MSG_RESULT and AC_DEFINE (see attached
patch). This happend on my LinuxPPC box.

This is the final state of the rule system for 6.4 after the
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.

just that the regression tests for rules work, please apply
the following to regress/sql/tests.
If applying by hand note that the setup_... must run before
the run_... (that I splitted these two was due to the errors
that occured when creating rules and using them then in the
same session - I'll post another fix for this later).
BTW: the regression tests sanity_checks and alter_table fail
now due to the remove of some indices and the oidint4 and
oidname types. At least expectes should be set to the current
results.

o note that now pg_database has a new attribuite "encoding" even

Bruce's massive patch, I think) BTW, I noticed that after running
regression, the oid field of pg_type seems disappeared.
regression=> select oid from pg_type; ERROR: attribute

this happens after the constraints test. This occures with/without
my patches. strange...
o pg_database_mb.h, pg_class_mb.h, pg_attribute_mb.h are no longer

o GetDatabaseInfo() in utils/misc/database.c removed (actually in
#ifdef 0). seems nobody uses.

Attached is a patch that uses autoconf to determine whether there
is a working 64-bit-int type available.
In playing around with it on my machine, I found that gcc provides
perfectly fine support for "long long" arithmetic ... but sprintf()
and sscanf(), which are system-supplied, don't work :-(. So the
autoconf test program does a cursory test on them too.
If we find that a lot of systems are like this, it might be worth
the trouble to implement binary<->ASCII conversion of int64 ourselves
rather than relying on sprintf/sscanf to handle the data type.

As proposed, here is the current version of PL/pgSQL. The
test isn't that complete up to now, but I think it shows
enough of the capabilities of the module.
The Makefile assumes it is located in a directory under
pgsql/src/pl. Since it includes Makefile.global and
Makefile.port and doesn't use any own compiler/linker calls,
it should build on most of our supported platforms (I only
tested under Linux up to now). It requires flex and bison I
think. Maybe we should ship prepared gram.c etc. like for the
main parser too?

With the attached patch, I have verified that long (> 8char anyway)
usernames and passwords work correctly in both "password" and
"crypt" authorization mode. NOTE: at least on my machine, it seems
that the crypt() routines ignore the part of the password beyond
8 characters, so there's no security gain from longer passwords in
crypt auth mode. But they don't fail.
The login-related part of psql has apparently not been touched
since roughly the fall of Rome ;-). It was going through huge
pushups to get around the lack of username/login parameters to
PQsetdb. I don't know when PQsetdbLogin was added to libpq, but
it's there now ... so I was able to rip out quite a lot of crufty
code while I was at it.
It's possible that there are still bogus length limits on username
or password in some of the other PostgreSQL user interfaces besides
psql/libpq. I will leave it to other folks to check that code.

<for details: see message, in pgsql-patches archive for above data>
Here is some more contrib-fodder, based on TIH's IP address type,
for ISBN and ISSN identifiers (which I just happened to need to keep
track of the things in my library).
Allow a null pointer to be returned from get_opname().
Previously, had thrown an error, but looking for alternate strategies
for table indices utilization would prefer to continue.
Check for null pointer returned from get_opname().
Don't bother checking for alternate strategies if so
since it was more likely a function or some other non-operator anyway.
Disable not-ready-to-use support code for the line data type.
Bracket things with #ifdef ENABLE_LINE_TYPE.
The line data type has always been used internally to support other types,
but I/O routines have never been defined for it.
Include a sentence in the top pointing to the new docs.
pgbuiltin.3 is obsolete for sure, and libpq.3 can become so since the
size and scope of this man page is not appropriate in a man page format.
Information moved to sgml source files.
The "Oracle compatibility" page should have always been in with functions
anyway. The BKI information is not really appropriate for a man page.
Nice exposition on indices and keys from Herouth Maoz which appeared
on the mailing lists a while ago. Maybe slightly changed to fit docs.
Will go into the User's Guide.
