Hi Peter, Thanks for the hint.
I can see that lc_collate (sorting) and lc_ctype (lower-upper conversion) is set to en_DK and I guess that default encoding for en_DK is iso88591 or maybe windows1252. Thus my server should have been initialized with en_DK.utf8 or? How do I find out what the default encoding for the locale en_DK is? I can see, that normally one would sub-specify this by either adding .iso88591 or .utf8, but is windows1252 then default? Because it is clear, that en_DK includes the proper rules for upper-lower conversion of Danish special characters as I when converting from UTF-8 to ISO 8859-1 can use upper() and lower() as expected. And Danish special characters have the same code points in latin1 and windows1252. I am not able to reinitdb, as many other databases are running, which might be affected negatively. This means, that even though my database is created WITH ENCODING 'unicode', it is in fact "broken" as the locale does not fully support unicode string handling? I wanted to use Unicode, as I expected non-latin1 characters, but this actually means, that if I had any such, some string functions would not work at all.

The lower case version of "ø" is of course just itself. This means you have mismatching server encodings and locales configured. Check SHOW lc_collate and SHOW server_encoding, and then pick a combination that is compatible. This will probably mean you have to reinitdb. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
