Re: how to make collation work - Mailing list pgsql-novice

Volkan,

I did not have the problem you had had, I mean the missing Hungarian
(Turkish in your case) capital letters. I can load them into the table, and
in the query all letters appear correctly, just the order is wrong.
As the docs says, for upper() and lower() the lc-ctype switch is
responsible. This determines what is a letter, and what letter is the
capital pair of another letter.
I have applied both lc-ctype, lc-collate switches with the hu_HU locale with
no result. I will check glibc. Thanks for the suggestion.

Best Regards,
Otto
