It seems https://gerrit.wikimedia.org/r/c/mediawiki/extensions/FlaggedRevs/+/110451/1/backend/schema/mysql/FlaggedRevs.sql never was applied to production. We need to run the schema change to actually fix it.
# **ALTERs to run:** TBD
# **Where to run those changes:** flaggedrevs.dblist
# **When to run those changes:** At any time
# **If the schema change is backwards compatible:** Yes.
# **If the schema change has been tested already on some of the test/beta wikis:** This has been around for ten years on new wikis.
# **if the data should be made available on the labs replicas and/or dumps:** The table only contains public data.
