AFAIK, Tom have fixed it, if this bug is about -funsigned-char

This isn't a "must fix for 7.1", any more than it was for 7.0, 6.5,
or any other release back to the beginning of time. It's always been
possible to crash the backend by passing an incompatible argument to
a type input or output function. The type-checking system cannot
detect the error because these functions are (mostly) declared to
take "any" input type (zero entry in proargtypes[]).
The only clean way to fix this is to declare I/O functions honestly.
That will require (a) a type-system representation for "C string"
and (b) a solution to the circularity issue for user-defined types.
If the I/O functions have to be declared first, how can they refer
to the type?
Quite aside from the time involved, this will require an initdb.
It's a bit late in the cycle for that.

Both password and username as well as line length and file length (in lines) have arbitrary limits, sometimes not even consistent ones. To fix this to a point where one is confident that everything works one essentially would have to rewrite the whole thing. > Does pg_dump preserve COMMENTs?

> Fix for pg_dump of bad system tables
Ok. I have made patches for fixing some of pg_dump problems(see
attached patches). The patches address the problem with user defined
functions, operators and aggregates. Could someone please review and
commit them if they look ok? (I'm now in US and have only very
expensive internet connection through an international phone call to
Japan in a hotel! Also I'm not quite sure "#arg" (stringification) is
portable enough in all platforms.) Or I could commit after going back
to Japan planned on Feb 2 if that's not too late.
However I have not address what Tom Lane said yet(actually I do not
understand what he says).

Depends on the definition of "bug". It's not spec compliant and it's not documented and it's annoying. But it's been like this for a year and the issue is well known and can normally be avoided. It looks like a documentation to-do to me. -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/

Do foreign keys reference just to a key value and are happy with it's existance, or do they refer to a particularrow? Consider you have a deferred "ON DELETE CASCADE" constraint and do a DELETE, INSERT of a PK. Do the FK rows needto be deleted or not? Consider you have a deferred "ON DELETE RESTRICT" and "ON UPDATE CASCADE" constraint. If you DELETE PK1 and UPDATEPK2 to PK1, the FK2 rows need to follow, but does PK2 inherit all FK1 rows now so it's the master of both groups? These are only two possible combinations. There are many to think of. As said, I've asked before, but noone voted yet. Move the item to 7.2 anyway, because changing this behaviour would require massive changes in the triggerqueue *and* the generic RI triggers, which cannot be tested enough any more.

The last is closer to OODBMS world, not to [O]RDBMS one. > Consider you have a deferred "ON DELETE CASCADE" constraint > and do a DELETE, INSERT of a PK. Do the FK rows need to be > deleted or not? Good example. I think FK should not be deleted. If someone really want to delete "old" FK then he can do DELETE PK; SET CONSTRAINT ...

Again one can use SET CONSTRAINT to achieve desirable results. It seems that SET CONSTRAINT was designed for these purposes - ie for better flexibility. Though, it would be better to look how other DBes handle all these cases -:) Vadim

I think I've been the main person arguing for this change, but I
agree with Jan that this late in the cycle is not the time to be
making such decisions. Let's discuss it again during 7.2 cycle.

Any pass-by-reference type; also most if not all input functions.

I was woundering if any of you have seen this problem. I have been running a system using a postgres 6.5 database. After a while I realized the system wasn't very active so I looked into it. I tryed to view all the tables in the database using the \d command, but it return: - Couldn't find any tables, sequences or indices! So I then tried to do a select statement from the table, which worked, although no data was returned, but the table structure was correct. I have backed up my database and have been trying to recover my data with no luck. I am able to vacuum the tables and have it tell me that there are several those tuples in each table, yet I still cant view the data. Any suggestions? Thanks, Stefan Klopp ecmarket

The patch looks fine to me, but I have no idea how portable #arg is - does
anybody else have some facts on the matter:
+#define AGG_NOTICE(arg) {\
+ fprintf(stderr, "Notice: aggregate \"%s\"(oid %s) is not
dumped.\n",agginfo[i].aggname, a
+ fprintf(stderr, "Reason: " #arg);\
+ fprintf (stderr, " (oid %s) not found.\n",agginfo[i].arg);\
+ }
+
It's easy enough to change the macros to take 2 params, and that would be
my inclination if it's not a solid part of the C standard (for any
non-trivial definintion of 'solid').

Use the CppAsString macro from our c.h ... that's what it's for.
It's actually fairly unlikely that anyone still uses a compiler that
doesn't grok #arg and yet can handle the other ANSI-isms that Postgres
requires. However, we may as well stick to the coding conventions
we have...

This refers to things like:
SELECT c.relname
FROM pg_index i, pg_class c
WHERE i.indrelid = %s
AND i.indisprimary
AND c.oid = i.indexrelid
ie. where two or more relations are crossed (pg_index and pg_class in this
case). It assumes that the metadata is valid, and will not highlight
missing data in the secondary table. We should be doing outer joins:
SELECT c.relname
FROM pg_index i LEFT OUTER JOIN pg_class c on c.oid = i.indexrelid
WHERE i.indrelid = %s
AND i.indisprimary
and checking for nulls using PQgetisnull. I have actually done this for a
couple of SELECTs (including the above one), and marked all the others as
'XXXX: use LOJ'. There are only 2 or 3 more, but they require a little more
thought (an inderstanding) before I change them.
In my view this should be considered a 'work-in-progress' and not hold up
7.1 since the problem has been there for a long time.

I assume this addresses the open item:
Fix for pg_dump of bad system tables
I will remove it from the list. Thanks.

I'd remove it from the 'Required for 7.1' list, but leave it on the TODO
list, since the task is not quite complete.

FYI, the "open" list are not all must-do items for 7.1. They are merely items that either need to be done, or moved to the TODO list. It is up to the group to decide which one they want. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026

BTW, are you going to make a back patch for the 7.0.x tree?

No more than in any prior release, AFAICS; these issues have been there
for a long time. I doubt that a back-patch is warranted.

Sorry for the delay, but this set of patches were targetted at trapping bad
metadata and as such are probably not appropriate for backporting. However,
some months ago, Tom did modify pg_dump for the new function manager
interface. It might be worth making a backpatch for this available.
