+postgresql 6.4 multi-byte (MB) support README Jul 22 1998

multi-byte character sets such as EUC(Extended Unix Code), Unicode and
Mule internal code. With the MB enabled you can use multi-byte
character sets in regexp ,LIKE and some functions. The encoding system
-chosen is determined at the compile time.
+chosen is determined when initializing your PostgreSQL installation
+using initdb(1). Note that this can be overrided when creating a
+database using createdb(1) or create database SQL command. So you
+could have multiple databases with different encoding system.
MB also fixes some problems concerning with 8-bit single byte
character sets including ISO8859. (I would not say all of problems
EUC_TW Taiwan EUC
UNICODE Unicode(UTF-8)
MULE_INTERNAL Mule internal
- LATIN1 ISO 8859-1 English and some European laguages
+ LATIN1 ISO 8859-1 English and some European languages
+ LATIN2 ISO 8859-2 English and some European languages
+ LATIN3 ISO 8859-3 English and some European languages
+ LATIN4 ISO 8859-4 English and some European languages
+ LATIN5 ISO 8859-5 English and some European languages
Example:
If MB is disabled, nothing is changed except better supporting for
8-bit single byte character sets.
-2. PGCLIENTENCODING
+2. How to set encoding
+
+initdb command defines the default encoding for a PostgreSQL
+installation. For example:
+
+ % initdb -e EUC_JP
+
+sets the default encoding to EUC_JP(Extended Unix Code for Japanese).
+Note that you can use "-pgencoding" instead of "-e" if you like longer
+option string:-) If no -e or -pgencoding option is given, the encoding
+specified at the compile time is used.
+
+You can create a database with a different encoding.
+
+ % createdb -E EUC_KR korean
+
+will create a database named "korean" with EUC_KR encoding. The
+another way to accomplish this is to use a SQL command:
+
+ CREATE DATABASE korean WITH ENCODING = 'EUC_KR';
+
+3. PGCLIENTENCODING
If an environment variable PGCLIENTENCODING is defined on the
frontend, automatic encoding translation is done by the backend. For
EUC_KR Korean EUC
EUC_TW Taiwan EUC
MULE_INTERNAL Mule internal
- LATIN1 ISO 8859-1 English and some European laguages
+ LATIN1 ISO 8859-1 English and some European languages
+ LATIN2 ISO 8859-2 English and some European languages
+ LATIN3 ISO 8859-3 English and some European languages
+ LATIN4 ISO 8859-4 English and some European languages
+ LATIN5 ISO 8859-5 English and some European languages
Note that UNICODE is not supported(yet). Also note that the
translation is not always possible. Suppose you choose EUC_JP for the
SET CLIENT_ENCODING TO 'encoding';
where encoding is one of the encodings those can be set to
-PGCLIENTENCODING. To query the current the frontend encoding:
+PGCLIENTENCODING. Also you can use SQL92 syntax "SET NAMES" for this
+purpose:
+
+ SET NAMES 'encoding';
+
+To query the current the frontend encoding:
SHOW CLIENT_ENCODING;
5. History
-Jun 5, 1988
+Jul 22, 1998
+ * determine encoding at initdb/createdb rather than compile time
+ * support for PGCLIENTENCODING when issuing COPY command
+ * support for SQL92 syntax "SET NAMES"
+ * support for LATIN2-5
+ * add UNICODE regression test case
+ * new test suite for MB
+ * clean up source files
+
+Jun 5, 1998
* add support for the encoding translation between the backend
and the frontend
* new command SET CLIENT_ENCODING etc. added

-# Create (initialize) a Postgres database system.
-#
-# A database system is a collection of Postgres databases all managed
-# by the same postmaster.
-#
-# To create the database system, we create the directory that contains
-# all its data, create the files that hold the global classes, create
-# a few other control files for it, and create one database: the
-# template database.
-#
-# The template database is an ordinary Postgres database. Its data
-# never changes, though. It exists to make it easy for Postgres to
-# create other databases -- it just copies.
-#
-# Optionally, we can skip creating the database system and just create
-# (or replace) the template database.
-#
-# To create all those classes, we run the postgres (backend) program and
-# feed it data from bki files that are in the Postgres library directory.
