Version: 0.91 for PgSQL 6.5
Author: Pavel Behal
Revised by: Tatsuo Ishii
Email: behal@opf.slu.cz
Licence: The Same as PostgreSQL

Sorry for my Eglish and C code, I'm not native :-)

!!!!!!!!!!!!!!!!!!!!!!!!! NO WARRANTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Instalation:
------------
1) Change three affected files in source directories 
    (I don't have time to create proper patch diffs, I don't know how)
	[PostgreSQL 6.5.1$B$G$O$3$N%9%F%C%W$OI,MW$"$j$^$;$s!#(B-- $B@P0f(B]
2) Compile with enabled locale and multibyte set to LATIN2
3) Setup properly your instalation, do not forget to create locale
   variables in your profile (environment). Ex. (may not be exactly true):
	LC_ALL=cs_CZ.ISO8859-2
	LC_COLLATE=cs_CZ.ISO8859-2
	LC_CTYPE=cs_CZ.ISO8859-2
	LC_MONETARY=cs_CZ.ISO8859-2
	LC_NUMERIC=cs_CZ.ISO8859-2
	LC_TIME=cs_CZ.ISO8859-2
4) You have to start the postmaster with locales set!
5) Try it with Czech language, it have to sort
5) Install ODBC driver for PgSQL into your M$ Windows
6) Setup properly your data source. Include this line in your ODBC
   configuration dialog in field "Connect Settings:" :
	SET CLIENT_ENCODING = 'WIN1250';
7) Now try it again, but in Windows with ODBC.

Description:
------------
- Depends on proper system locales, tested with RH6.0 and Slackware 3.6,
  with cs_CZ.iso8859-2 loacle
- Never try to set-up server multibyte database encoding to WIN1250,
  always use LATIN2 instead. There is not WIN1250 locale in Unix
- WIN1250 encoding is useable only for M$W ODBC clients. The characters are
  on thy fly re-coded, to be displayed and stored back properly
 
Important:
----------
- it reorders your sort order depending on your LC_... setting, so don't be
  confused with regression tests, they don't use locale
- "ch" is corectly sorted only in some newer locales (Ex. RH6.0)
- you have to insert money as '162,50' (with comma in aphostrophes!)
- not tested properly
