No, I doubt this.
Example: set up a cluster: $ initdb -E LATIN1 --locale=sv_SE.ISO8859-1 $ createdb foo CREATE DATABASE $ psql foo foo=# create table bar (val text); CREATE TABLE foo=# insert into bar values ('aaa'); INSERT 18354409 1 foo=# insert into bar values ('BBB'); INSERT 18354412 1 foo=# select val from bar order by val; val ----- BBB aaa (2 rows)
Order by is not case insensitive. It shouldn't be for any system, AFAIK. As
It is on my machine... for the same test:
foo=# select val from bar order by val; val ----- aaa BBB (2 rows)
I think this just implies even greater breakage of either the collation or strcoll on the system you're trying on. ;) Which, of course, is a fairly reasonable reason to offer an alternative. Especially if it's generically useful.
Interesting! Indeed, just tried on an old Linux Redhat system... BTW, that's pretty odd for a unix system. "ls -l" sorts aaa before BBB, I've never seen the likes of it! Call me old fashion if you like ;-)
Still, as you say, FreeBSD does it capital letters first, and does not handle unicode locales' collation, so I need an alternative. Perhaps the best way would be to inject ICU into BSD instead :-)
