After some playing with gdb I found that in printtup() there is a non null
attribute with typeinfo->attrs[i]->atttypid = 0 (invalid oid). Unfortunately
attibutes with invalid type are neither printed nor marked as null, and this
explains why psql doesn't get all the expected data.

Ok. BTW Mr. Kataoka who is maintaing Japanese version of PostgreSQL
ODBC driver have found a bug in 6.3.2 pg_dump and have made patches.
I confirmed that the same bug still exists in the current source
tree. So I made up patches based on Kataoka's. Here are some
explanations.
o fmtId() returns pointer to a static memory in it. In the meantime
there is a line where is fmtId() called twice without saving the
first value returned by fmtId(). So second call to fmtId() will
break the first one.
o findTableByName() looks up a table by its name. if a table name
contanins upper letters or non ascii chars, fmtId() will returns
a name quoted in double quotes, which will not what findTableByName()
wants. The result is SEG fault. -- Tatsuo Ishii t-ishii@sra.co.jp

Hello!
Here is a new patch for libpq, to make it work on Win32 again (since
the latest modifications broke it a little).
Please also add the file "libpq.rc" to the interfaces/libpq directory.
This will allow version-stamping of the generated DLL file, so that
automatic install programs (and interested users) can determine
the version of the file. The file is currently set as "prerelease".
Before the release, somebody should change the line "FILEFLAGS
VS_FF_PRERELEASE" to "FILEFLAGS 0". That information should probably
go into toos\RELEASE_CHANGES.
The patch is against the cvs as of ~ 1998-08-26 14:30 CEST.

Hi all,
I don't know if this is really related to the initdb problem
discussion (haven't followed it enough). But seems so because
it fixes a damn problem during index tuple insertion on
CREATE TABLE into pg_attribute_relid_attnum_index.
Anyway - this bug was really hard to find. During startup the
relcache reads in some prepared information about index
strategies from a file and then reinitializes the function
pointers inside the scanKey data. But for sake it assumed
single attribute index tuples (hasn't that changed recently).
Thus not all the strategies scanKey entries where initialized
properly, resulting in invalid addresses for the btree
comparision functions.
With the patch at the end the regression tests passed
excellent except for the sanity_check that crashed at vacuum
and the misc test where the select unique1 from onek2 outputs
the two rows in different order.

(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,
so missed some cases.

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.

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.
