[wp-polyglots] Un-i18n-ed string

[Mohd Tarmizi]

The end of wp-includes/functions.php contains untranslatable messages 
(i.e. "Database Error", "Error establishing a database connection"), but 
the Codex ([1]) makes no mention of it. Should I update the Codex page 
to include this file, or should I file a bug/patch at Trac to make these 
messages translatable, or are they not meant to be translated?

I noticed that the error happens when wp-config.php is not configured 
properly.
