Due to T157651: sql.php must not run LoadExtensionSchemaUpdates causing the drop of a table in production T249565: Wikidata's wb_items_per_site table has suddenly disappeared, creating DBQueryErrors on page views, one of the action items is to remove DROP and ALTER grant from the wikiadmin user.
This is what wikiadmin user currently have:
GRANT ALL PRIVILEGES ON `%wik%`.*
We should probably limit it to:
- REPLICATION CLIENT
- CREATE TEMPORARY TABLES
