Many moons ago, the MediaWiki extension [[mw:Extension:PovWatch]] was installed on a few Wikimedia wikis. It's long since been disabled.
The PovWatch MediaWiki extension has two database tables that appear at least on testwiki, commonswiki and enwiki:
- povwatch_log
- povwatch_subscribers
These database tables should be dropped from all Wikimedia wiki databases.
Version: wmf-deployment
Severity: enhancement
