Missed a few files in the last round of commits from Tatsuo, as well
as needed to run autoconf ...

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).

I missed addding initdb.sh ...

statements.  More cleanups of psql help.  Fix for shift/reduce on
UNION in subselect.

manual pages.

Everyone using an [NOT] EXISTS subquery will have noticed that
already.

The bug is in "subselect.c" in the function "SS_process_sublinks()".

Here the whole function as it *SHOULD BE*:

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.

calls. Outside a transaction, the backend detects them as buffer
leaks; it sends a NOTICE, and frees them. This sometimes cause a
segmentation fault (at least on Linux). These indexes are initialized
on the first lo_read/lo_write/lo_tell call, and (normally) closed
on a lo_close call.  Thus the buffer leaks appear when lo direct
access functions are used, and not with lo_import/lo_export functions
(libpq version calls lo_close before ending the command, and the
backend version uses another path).

The included patches (against recent snapshot, and against 6.3.2)
cause indexes to be closed on transaction end (that is on explicit
'END' statment, or on command termination outside trasaction blocks),
thus preventing the buffer leaks while increasing performance inside
transactions. Some (all?) 'classic' memory leaks are also removed.

I hope it will be ok.

inclusion in pgsql. I have included a README which should be enough
to start using it, plus a BENCH file that describes some timings
I have done.

Please have a look at it, and if you think everything is OK, I
would like it seen included in the contrib-section of pgsql.

I don't think I will do any more work in this, but maybe it inspires
somebody else to improve on it.

   now. Here some tested features, (examples included in the patch):

1.1) Subselects in the having clause 1.2) Double nested subselects
1.3) Subselects used in the where clause and in the having clause
     simultaneously 1.4) Union Selects using having 1.5) Indexes
on the base relations are used correctly 1.6) Unallowed Queries
are prevented (e.g. qualifications in the
     having clause that belong to the where clause) 1.7) Insert
into as select

2) Queries using the having clause on view relations also work
   but there are some restrictions:

2.1) Create View as Select ... Having ...; using base tables in
the select 2.1.1) The Query rewrite system:

2.1.2) Why are only simple queries allowed against a view from 2.1)
? 2.2) Select ... from testview1, testview2, ... having...; 3) Bug
in ExecMergeJoin ??

of days --- it was emitting stuff like
	REVOKE ALL on 'table' from PUBLIC; GRANT ALL on "table" to
	"Public"; neither of which work.  While I was at it I
cleaned up a few other things:

* \connect commands are issued only in -z mode.  In this way,
reloading a pg_dump script made without -z will generate a simple
database wholly owned by the invoking user, rather than a mishmash
of tables owned by various people but lacking in access rights.
(Analogy: cp versus cp -p.)

* \connect commands are issued just before COPY FROM stdin commands;
without this, reloading a database containing non-world-writable
tables tended to fail because the COPY was not necessarily attempted
as the table owner.

* Redundant \connect commands are suppressed (each one costs a
backend launch, so...).

* Man page updated (-z wasn't ever documented).

The first two items were discussed in a pgsql-hackers thread around
6 May 98 ("An item for the TODO list: pg_dump and multiple table
owners") but no one had bothered to deal with 'em yet.
