| MediaWiki version: |
≥ 1.18 |
Stores the groups the user has once belonged to (will not contain groups the user had belonged to before MW 1.17). The user may again belong to these groups; check the table user_groups, if you want to know. This is used to keep MediaWiki from automatically adding users to groups from which he has been manually removed before. The table was added in r90749.
[edit] Schema summary
- ufg_user: Key to user_id.
- ufg_group: Name of the group, which the user was member of.
