While, right now, sites using long (> 10 chars) $CFG->prefix can continue working (because we still don't have any table > 28 chars), as soon as some new table with long name is added, it won't work with PostgreSQL anymore (if the 63 limit is raised). Hence, this environmental check will verify on both install and upgrade that the $CFG->prefix is always <= 10 chars. Sites with longer prefixes will need to rename all their tables (and maybe other objects, depending on the dbtype) to use a shorter prefix.
Moodle Language Packs
This directory contains the standard packaged Moodle language files,
for making the Moodle interface appear in different interfaces.
The default language for Moodle is the English language, under the
Unicode scheme (UTF8).
To add more languages to Moodle, you can either:
1) use the Moodle languages GUI in the interface to fetch
new languages and install them in your 'dataroot' directory.
2) download them and unzip the packs in this directory manually
For more information, see the Moodle Documentation:
