Re: [PATCHES] [HACKERS] WITH RECURSIVE updated to CVS TIP
Here is the patches he made against CVS HEAD (as of today). According to him followings are fixed with the patches: - fix crush with DISTINCT - fix creating VIEW - fix the case when recursion plan has another recursion plan under it - fix WITH RECURSIVE ...(..) SELECT ...WHERE.. returns wrong result - fix inifinit recursion with OUTER JOIN Not yet fixed: - detect certain queries those are not valid acroding to the standard - sort query names acording to the dependency - planner always estimate 0 cost for recursion plans -- Tatsuo Ishii SRA OSS, Inc.

Re: [PATCHES] Extending grant insert on tables to sequences

Hi,
The idea of this patch is to avoid the need to make explicit grants on
sequences owned by tables.
I've noted that the patch i attached is an older version that doesn't
compile because of a typo...
Re-attaching right patch and fix documentation to indicate the new
behaviour...
I had a look at this patch and it looks good. The only thing that's not
clear to me is whether we have agreed we want this to be the default
behavior?
A quibble:
+ foreach(cell, istmt.objects)
+ {
+ [...]
+
+ istmt_seq.objects = getOwnedSequences(lfirst_oid(cell));
+ if (istmt_seq.objects != NIL)
+ {
+ if (istmt.privileges (ACL_INSERT))
+ istmt_seq.privileges |= ACL_USAGE;
+ else if (istmt.privileges (ACL_UPDATE))
+ istmt_seq.privileges |= ACL_UPDATE;
+ else if (istmt.privileges (ACL_SELECT))
+ istmt_seq.privileges |= ACL_SELECT;
+
+ ExecGrantStmt_oids(istmt_seq);
+ }
Wouldn't it be clearer to build a list with all the sequences owned by
the tables in istmt.objects, and then call ExecGrantStmt_oids() a single
time with the big list?

[PATCHES] Add missing descriptions for aggregates, functions and conversions
Please find attached a patch that adds some missing descriptions for aggregates, functions and conversions. This will add COMMENTs to the conversion sql script as well. Most of the descriptions are taken from the documentation (especially for the statistic functions). I didn't bother with some internal functions like text_pattern_lt, if we agree they should be described as well i can add them, too. -- Thanks Bernd? function_descr.patch Index: src/backend/utils/mb/conversion_procs/Makefile === RCS file: /projects/cvsroot/pgsql/src/backend/utils/mb/conversion_procs/Makefile,v retrieving revision 1.19 diff -c -b -r1.19 Makefile *** src/backend/utils/mb/conversion_procs/Makefile 18 Mar 2008 16:24:50 - 1.19 --- src/backend/utils/mb/conversion_procs/Makefile 8 Jul 2008 15:06:47 - *** *** 175,182 --- 175,184 obj=$$1; shift; \ echo -- $$se -- $$de; \ echo CREATE OR REPLACE FUNCTION $$func (INTEGER, INTEGER, CSTRING, INTERNAL, INTEGER) RETURNS VOID AS '$$libdir/$$obj', '$$func' LANGUAGE C STRICT;; \ + echo COMMENT ON FUNCTION $$func(INTEGER, INTEGER, CSTRING, INTERNAL, INTEGER) IS 'internal conversion function for $$se to $$de';; \ echo DROP CONVERSION pg_catalog.$$name;; \ echo CREATE DEFAULT CONVERSION pg_catalog.$$name FOR '$$se' TO '$$de' FROM $$func;; \ + echo COMMENT ON CONVERSION pg_catalog.$$name IS 'conversion for $$se to $$de';; \ done $@ else echo -- No conversion support, for lack of shared library support $@ Index: src/include/catalog/pg_proc.h === RCS file: /projects/cvsroot/pgsql/src/include/catalog/pg_proc.h,v retrieving revision 1.504 diff -c -b -r1.504 pg_proc.h *** src/include/catalog/pg_proc.h 3 Jul 2008 20:58:46 - 1.504 --- src/include/catalog/pg_proc.h 8 Jul 2008 15:06:47 - *** *** 235,241 DATA(insert OID = 110 ( unknownout PGNSP PGUID 12 1 0 f f t f i 1 2275 705 _null_ _null_ _null_ unknownout - _null_ _null_ )); DESCR(I/O); DATA(insert OID = 111 ( numeric_fac PGNSP PGUID 12 1 0 f f t f i 1 1700 20 _null_ _null_ _null_ numeric_fac - _null_ _null_ )); !

Re: [PATCHES] [HACKERS] Solaris ident authentication using unix domain sockets
Tom, Indeed. If the Solaris folk feel that getupeercred() is insecure, they had better explain why their kernel is that broken. This is entirely unrelated to the known shortcomings of the ident IP protocol. The Solaris security kernel folks do, actually. However, there's no question that TRUST is inherently insecure, and that's what people are going to use if they can't get IDENT to work. -- Josh Berkus PostgreSQL @ Sun San Francisco -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches

Do the Solaris devs think that their getupeercred() is more insecure than the more or less equivalent calls that we are doing on Linux and *BSD for example? I suspect they probably don't ;-) cheers andrew -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches
