lock.patch
I have rewritten lock.c cleaning up the code and adding better
assert checking I have also added some fields to the lock and
xid tags for better support of user locks. There is also a new
function which returns an array of pids owning a lock.
I'm using this code from over six months and it works fine.
assert.patch
adds a switch to turn on/off the assert checking if enabled at compile
time. You can now compile postgres with assert checking and disable it
at runtime in a production environment.
(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
and local1_template1.description
stderr has to be redirected to /dev/null:

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.

Thanks. But patches for src/backend/catalog/Makefile seems missing
in the current source tree. Please apply attached patches.
It also includes some corrections to src/backend/util/mb/wchar.c.

[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.

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.

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.
Thanks.

if MULTIBYTE is not enabled. So be sure to run initdb.
o these patches are made against the latest source tree (after
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
'oid' not found
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
used, and shoud be removed.
o GetDatabaseInfo() in utils/misc/database.c removed (actually in
#ifdef 0). seems nobody uses.

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.

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.

with the new support for asynchronous NOTIFY in libpgtcl. With
the current sources, if the backend disconnects unexpectedly then
the tcl/tk application coredumps when control next reaches the idle
loop. Oops.

Summary of changes:
In pqcomm.h, use the SUN_LEN macro if it is defined to calculate
the size of the sockaddr_un structure.
In unixware.h, drop the use of the UNIXWARE macro. Everything can
be handled with the USE_UNIVEL_CC and DISABLE_COMPLEX_MACRO macros.
In s_lock.h, remove the reference to the UNIXWARE macro (see above).
In the unixware template, add the YFLAGS:-d line.
In various makefile templates, add (or cleanup) unixware and univel
port specific information.

From: Tom Lane <tgl@sss.pgh.pa.us>
Attached is a patch for this weekend's work on libpq. I've dealt
with several issues:

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.
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.

Had to rerun ldconfig on my machine to get it working again.
Give an error message with a helpful hint if so...
functions btrim() ltrim() and rtrim().
The error was that the character after the set was included
in the tests (ptr2 pointed to the character after the vardata
part of set if no match found, so comparing *ptr or *end
against *ptr2 MAY match -> strip).

couple weeks ago on the hackers and interfaces lists:
1. When the backend sends a NOTICE message and closes the connection
(typically, because it was told to by the postmaster after
another backend coredumped), libpq will now print the notice
and close the connection cleanly. Formerly, the frontend app
would usually terminate ungracefully due to a SIGPIPE. (I am
not sure if 6.3.2 behaved that way, but the current cvs sources
do...)
2. libpq's various printouts to stderr are now fed through a single
"notice processor" routine, which can be overridden by the
application to direct notices someplace else. This should ease
porting libpq to Windows.
I also noticed and fixed a problem in PQprint: when sending output
to a pager subprocess, it would disable SIGPIPE in case the pager
terminates early (this is good) --- but afterwards it reset SIGPIPE
to SIG_DFL, rather than restoring the application's prior setting
(bad).
