Steps to replicate the issue (include links if applicable):

I have a private MediaWiki Installation and want to upgrade it from Version 1.39 to 1.43.3 - Now comes an Error, and I have no ssh-access, to run the php updatescript. I try to
update the database by the installer in the new version, by desactivating the old localsettings.....

What happens?:
This error appears: (chronik_ is the database-prefix)

Error 1062: Duplicate entry '1' for key 'chronik_pagelinks.pl_from'
Function: Wikimedia\Rdbms\Database::sourceFile( /var/www/ud05_173/html/mediawiki/maintenance/archives/patch-pagelinks-drop-pl_title.sql )
Query: ALTER TABLE chronik_pagelinks
DROP pl_namespace,
DROP pl_title,
CHANGE pl_target_id pl_target_id BIGINT UNSIGNED NOT NULL

What should have happened instead?:

DAtabase successfully updated..... :-)
