You can make this work with some help from your OS.  Have your locale set
correctly to recognize non-ascii characters when postmaster starts.  I did
it by setting LC_CTYPE to iso_8859_1 in the postgres superuser's shell
initialization file.  Note that this won't work unless the locale is
actually available on your machine; you can't just type the same thing I
did and hope for the best.


If it helps, this is from the postgres superuser's shell at our site:
[1:42pm] /data/postgres> uname -a
SunOS ptolemy.tlg.uci.edu 5.6 Generic_105181-08 sun4u sparc SUNW,Ultra-5_10

[1:43pm] /data/postgres> locale
LANG=
LC_CTYPE=iso_8859_1
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_ALL=

This is not a complete solution (collation is still incorrect) but it
should get you started.  Hope it helps.

Gert (or anyone): what should the result be? I'm German-impaired, so
you'll need to be more specific. Did you compile with locale turned on?
Multi-byte character sets?? Which byte codes correspond to the lower-
and upper-case umlaut characters???

You need to enable locale support (see documentation).
