Well, the comparison function varstr_cmp() contains this comment: /* * In some locales strcoll() can claim that nonidentical strings are * equal. Believing that would be bad news for a number of reasons, * so we follow Perl's lead and sort "equal" strings according to * strcmp(). */ This might not be strictly necessary, seeing that citext obviously doesn't work that way, but resolving this is really an orthogonal issue. If you fix that and you have a locale that does what you want, my patch will help you get your example working. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
