Description

With T299417 the tl_namespace and tl_title fields are removed from templatelinks, but are refered by cleanupInvalidDbKeys.php.

The script should cleanup the new linktarget as well, when something invalid is there

sigh, that's important because if it's ran on basically any section now and it does a write on the table, it'd break replication to all replicas...

at least as silver lining, it breaks before even getting into deleting stuff.

The clean up from linktarget table will happen with a dedicated maint script that removes all orphan linktarget rows. This is done.
