Обсуждение: Create collation incorrect error code

Strangeness:

template1=# create collation "nb_NO.utf8" (locale=nb_NO.utf8);
ERROR:  could not create locale "nb_no.utf8": Success

Clearly it's not successful...

On some runs, I get:

template1=# create collation "nb_NO.utf8" (locale=nb_NO.utf8);
ERROR:  could not create locale "nb_no.utf8": No such file or directory
DETAIL:  The operating system could not find any locale data for the
locale name "nb_no.utf8".

Which is correct.

The first one is clearly wrong. Seems there are some cases where errno
isn't set properly? But form what I can tell
(http://pubs.opengroup.org/onlinepubs/9699919799/functions/newlocale.html)
errno should be set.

FWIW, I get the same on Fedora 16.  It works if I say
locale='nb_NO.utf8' to prevent case-folding, so apparently case of the
locale name has something to do with it ...

This seems to be a glibc bug: it won't set errno correctly
if you've already asked about the same wrong locale name.  Filed at
https://bugzilla.redhat.com/show_bug.cgi?id=827510
