Обсуждение: Missing locale files according to psql

I've been troubleshooting some connection problems with one of our servers recently, and as part of the effort, I ran
psqlthrough strace in order to see what was going on. Oddly  
enough, I saw a bunch of "problems". The output contained:

open("/usr/pgsql-9.3/share/locale/en_US.UTF-8/LC_MESSAGES/pgsql-9.3.mo", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/usr/pgsql-9.3/share/locale/en_US.utf8/LC_MESSAGES/pgsql-9.3.mo", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/usr/pgsql-9.3/share/locale/en_US/LC_MESSAGES/pgsql-9.3.mo", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/pgsql-9.3/share/locale/en.UTF-8/LC_MESSAGES/pgsql-9.3.mo", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/pgsql-9.3/share/locale/en.utf8/LC_MESSAGES/pgsql-9.3.mo", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/pgsql-9.3/share/locale/en/LC_MESSAGES/pgsql-9.3.mo", O_RDONLY) = -1 ENOENT (No such file or directory)

I looked in /usr/pgsql-9.3/share/locale and only saw "cs    de es       fr    it    ja    pl     pt_BR        ro    ru
 sv tr    zh_CN    zh_TW" 
but nothing looking like en* anything. Now, my connection problem is only with one server, and psql works to other 2
servers,but what should I have in the locale directory? After  
the above error block, it appears that psql gives up and just continues initializing. I don't see any more attempts to
loadan locale files. If it makes a difference, this is  
postgreSQL 9.3.3 on CentOS 6.5 loaded via yum installs.

This is not a problem.  It's looking for message translation files for
en_US, but if they are not there, it will proceed without them.

Ok, enough, but if they're not included in the PostgreSQL rpm, why does psql look for them?

This is how locales work, independent of PostgreSQL or psql.  You set a
locale in the environment, the operating system looks if locale
information files are installed, and if not in proceeds with a fallback.

Perhaps more to the point: there is a defined search path that libc is
supposed to follow when looking to see if there is a messages file for
the application.  It does not know in advance whether the app has a
messages file or exactly where in the path it'll be located.
