Checking whith ps and looking in /proc reveiled that postmaster indeed
had LANG set to "en_US" in its environment.  I disabled the system script
that makes this setting, restarted postgres/postmaster and reran my tests.

The problem query returns the *right* answer now !
Turning LANG=en_US back on gives the old buggy behaviour.

I know very little about this LANG, LOCALE etc. stuff.
But for our application it is very important to support "weird" characters
like "���� ..." etc. for names.  Basically we need all letter symbols
in ISO-8859-1 (Latin 1).  A quick experiment shows that without the
LANG setting I can still insert & select strings containing these
symbols.

Do I lose any postgresql functionality by just getting rid of the LANG
environment variable ?  Will I be able to use full ISO-8859-1 in table
fields without problems ?

Please tell if you want me to do any other tests !
