Обсуждение: PostgreSQL v7.2 Final Release
For Immediate Release February 5th, 2002
After almost a full year of development since PostgreSQL v7.1 was
released, the PostgreSQL Global Development Group is proud to announce the
availability of our latest development milestone ... PostgreSQL v7.2,
another step forward for the project.
A full list of changes to v7.2 can be found in the HISTORY file,
included with the release, as well as under all ftp mirrors as:
/pub/README.v7_2
Highlights of this release are as follows:
VACUUM
Vacuuming no longer locks tables, thus allowing normal user
access during the vacuum. A new "VACUUM FULL" command does
old-style vacuum by locking the table and shrinking the on-disk
copy of the table.
Transactions
There is no longer a problem with installations that exceed
four billion transactions.
OID's
OID's are now optional. Users can now create tables without
OID's for cases where OID usage is excessive.
Optimizer
The system now computes histogram column statistics during
"ANALYZE", allowing much better optimizer choices.
Security
A new MD5 encryption option allows more secure storage and
transfer of passwords. A new Unix-domain socket authentication
option is available on Linux and BSD systems.
Statistics
Administrators can use the new table access statistics module
to get fine-grained information about table and index usage.
Internationalization
Program and library messages can now be displayed in several
languages.
.. with many many more bug fixes, enhancements and performance
related changes ...
Source for this release is available on all mirrors under:
/pub/source/v7.2
As always, any bugs with this release should be reported to
pgsql-bugs@postgresql.org ... and, as with all point releases, this
release requires a complete dump and reload from previous releases, due to
internal structure changes ...

Oh, I'm building NLS-capable RPM's as I write this; expect an upload shortly. The NLS file list mechanism munged the execute permission for the initscript, so I had to track that down before release.

FWIW, the python rpms in Rawhide have static libraries, but are compiled with -fPIC.

Don't check in any 7.3 development until we split off a CVS branch for
7.2 maintenance. We'll probably wait at least a week before we do that;
longer if it looks like there are lots of problems...

Please refrain from language flames...the pgsql lists are exceptional
lists that really don't need this pollution.

Please read the README.rpm-dist and CHANGELOG files in the above referenced directory for more information. Bug reports to either pgsql-bugs or pgsql-ports, please. RPMs for redhat-6.2 will be available shortly. Note that you may need to update OS utilities to rebuild from source on Red Hat 6.2. An updated patch utility is known to be necessary.

Thanks to Dr. Rich Shepard, we have Red Hat 6.2 binary RPMs, built for i386, i586, and i686 architectures. If there is demand, I will attempt a build for SuSE 7.3 on UltraSPARC. I also am looking at Caldera builds (thanks to Larry Rosenman). Mandrake 8.0 RPMs should be built shortly, thanks to Justin Clift. Thomas Lockhart typically does Mandrake 7.2. For Thomas and other PostgreSQL developers who are members of the pgsql group on the dev server, the dirs are g+w for the binaries. Exciting times! -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

I found that in order to rebuild the 7.2.src.rpm I had to upgrade my
'patch' utility. The one I had installed was version 2.5-9 (the package
build); the one I built from the .src.rpm is 2.5.4. As soon as I freshened
the installation, the command 'rpm --rebuild ...' worked just fine.
However, there's a problem with 'gettext' that I didn't resolve.
Apparently RH 6.2's version is too old, but trying to rebuild the
gettext.src.rpm kept failing. Rather than futz with that, too, I changed the
spec file so !nls = 0} and I commented out the line requiring gettext.
If you do this, you need to rebuild the packages from the
/usr/src/redhat/SPECS/ directory with the command, 'rpm -ba [--target=iX86]
...'. However, the full set of binary packages for i386, i586, and i686 are
on the postgres ftp server. The i686 version freshened our installation from
7.1.3 to 7.2 flawlessly.
Glad to contribute,

The following seems to be a bug in 7.2 (and in 7.1.2) I'm pretty sure it worked before, certainly it's something I do a lot (but postgresql isn't the only database I use). The bug concerns a NOT IN on a list generated by a select. If you have two tables thus: create table t1 (id integer, name varchar(20), t2_id integer); insert into t1 (id, name, t2_id) values (1, 'nic', 2); insert into t1 (id, name, t2_id) values (2, 'jim', NULL); create table t2 (id integer, name varchar(20)); insert into t1 (id, name, t2_id) values (1, 'ferrier'); insert into t1 (id, name, t2_id) values (2, 'broadbent'); And now do this query: select * from t2 where id not in (select t2_id from t1); then I get a NULL response (ie: no rows returned). What I SHOULD get is the row from t2 with id == 2; Nic Ferrier

Well, you never inserted any rows into t2, so that makes sense. -Doug -- Doug McNaught Wireboard Industries http://www.wireboard.com/ Custom software development, systems and network consulting.

No, you should not; the system's response is correct per spec.
For the t2 row with id=2, the WHERE clause is clearly FALSE
(2 is in select t2_id from t1). For the t2 row with id=1,
the WHERE clause yields UNKNOWN because of the NULL in t1,
and WHERE treats UNKNOWN as FALSE. This has been discussed
before on the lists, and it's quite clear that the result is
correct according to SQL's 3-valued boolean logic.
There are a number of ways you could deal with this. If you
simply want to ignore the NULLs in t1 then you could do either
select * from t2 where id not in (select distinct t2_id from t1);
select * from t2 where (id in (select t2_id from t1)) is not false;
The first of these will probably be faster if there aren't many
distinct t2_id values.

Because there's a NULL in the output of the subselect, NOT IN is never going to return rows and this is correct. The transformations by the spec start out: RVC NOT IN IPV => NOT (RVC IN IPV) => NOT (RVC =ANY IPV) The result of RVC =ANY IPV is derived from the application of = to each row in IPV. If = is true for at least one row RT of IPV then RVC =ANY IPV is true. If IPV is empty or if = is false for each row RT of IPV then RVC =ANY IPV is false. If neither of those cases hold, it's unknown. Since anything = NULL returns unknown, not false, the last case is the one that holds. You then NOT the unknown and get unknown back. Where clauses don't return rows where the condition is unknown, so you won't get any rows back.
Whoops! Thanks Tom (and everyone else who replied) And apoloies for the dumb mistake with the inserts (I could try and pretend it was a deliberate mistake but since I made an even bigger error I won't do that). Nic
