b4a607c9e0 Modify RelationFlushRelation so that if the relcache entry
has positive refcount, it is rebuilt from pg_class data.  This ensures
that relcache entries will track changes made by other backends.  Formerly,
a shared inval report would just be ignored if it happened to arrive while
the relcache entry was in use.  Also, fix relcache to reset ref counts
to zero during transaction abort.  Finally, change LockRelation() so that
it checks for shared inval reports after obtaining the lock.  In this way,
once any kind of lock has been obtained on a rel, we can trust the relcache
entry to be up-to-date.

68c323483c Repair a bunch of problems in md.c. This builds on Hiroshi's
insight that RelationFlushRelation ought to invoke smgrclose, and that the
way to make that work is to ensure that mdclose doesn't fail if the relation
is already closed (or unlinked, if we are looking at a DROP TABLE).  While
I was testing that, I was able to identify several problems that we had
with multiple-segment relations.  The system is now able to do initdb and
pass the regression tests with a very small segment size (I had it set to
64Kb per segment for testing).  I don't believe that ever worked before.
File descriptor leaks seem to be gone too.
I have partially addressed the concerns we had about mdtruncate(), too.
On a Win32 or NFS filesystem it is not possible to unlink a file that
another backend is holding open, so what md.c now does is to truncate
unwanted files to zero length before trying to unlink them.  The other
backends will be forced to close their open files by relation cache
invalidation --- but I think it would take considerable work to make
that happen before vacuum truncates the relation rather than after.
Leaving zero-length files lying around seems a usable compromise.

87d95ca04d Arrange for VACUUM to delete the init file that relcache.c uses
to save a little bit of backend startup time.  This way, the first
backend started after a VACUUM will rebuild the init file with up-to-date
statistics for the critical system indexes.

a53ea467e1 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.

c0b01461db o note that now pg_database has a new attribuite "encoding" even
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.

5979d73841 From: t-ishii@sra.co.jp
As Bruce mentioned, this is due to the conflict among changes we made.
Included patches should fix the problem(I changed all MB to
MULTIBYTE). Please let me know if you have further problem.

P.S. I did not include pathces to configure and gram.c to save the
file size(configure.in and gram.y modified).

bf00bbb0c4 I really hope that I haven't missed anything in this one...
From: t-ishii@sra.co.jp

Attached are patches to enhance the multi-byte support.  (patches are
against 7/18 snapshot)

* determine encoding at initdb/createdb rather than compile time

Now initdb/createdb has an option to specify the encoding. Also, I
modified the syntax of CREATE DATABASE to accept encoding option. See
README.mb for more details.

For this purpose I have added new column "encoding" to pg_database.
Also pg_attribute and pg_class are changed to catch up the
modification to pg_database.  Actually I haved added pg_database_mb.h,
pg_attribute_mb.h and pg_class_mb.h. These are used only when MB is
enabled. The reason having separate files is I couldn't find a way to
use ifdef or whatever in those files. I have to admit it looks
ugly. No way.

* support for PGCLIENTENCODING when issuing COPY command

commands/copy.c modified.

* support for SQL92 syntax "SET NAMES"

See gram.y.

* support for LATIN2-5
* add UNICODE regression test case
* new test suite for MB

New directory test/mb added.

* clean up source files

Basic idea is to have MB's own subdirectory for easier maintenance.
These are include/mb and backend/utils/mb.
