* migrateUserGroup.php: Call User::invalidateCache
* While at it, also fix the issue where User::clearInstanceCache
did not clear cache for User::getGroups.
Although it does clear the caches of methods used to calculate
other group-related lists (such as User::getEffectiveGroups),
the one for the query from user_groups was still cached in
$this->mGroups.
Presumably this was forgotten when this pattern was introduced
as the instance cache precedes the user_group table.

== MediaWiki Maintenance ==
The .sql scripts in this directory are not intended to be run standalone,
although this is appropriate in some cases, e.g. manual creation of blank tables
prior to an import.
Most of the PHP scripts need to be run from the command line. Prior to doing so,
ensure that the LocalSettings.php file in the directory above points to the
proper installation.
Certain scripts will require elevated access to the database. In order to
provide this, first create a MySQL user with "all" permissions on the wiki
database, and then set $wgDBadminuser and $wgDBadminpassword in your
LocalSettings.php
=== Brief explanation of files ===
A lot of the files in this directory are PHP scripts used to perform various
maintenance tasks on the wiki database, e.g. rebuilding link tables, updating
the search indices, etc. The files in the "archives" directory are used to
upgrade the database schema when updating the software. Some schema definitions
for alternative (as yet unsupported) database management systems are stored
here too.
The "storage" directory contains scripts and resources useful for working with
external storage clusters, and are not likely to be particularly useful to the
vast majority of installations. This directory does contain the compressOld
scripts, however, which can be useful for compacting old data.
=== Maintenance scripts ===
As noted above, these should be run from the command line. Not all scripts are
listed, as some are Wikimedia-specific, and some are not applicable to most
installations.
