It seems there are some incorrect data there.

So the "swauthor swauthor_namesite_unique index-columns-mismatch" is still there.

On https://gerrit.wikimedia.org/r/c/mediawiki/extensions/CreditsSource/+/31026 there was a change to add a new column

DROP /*i*/INDEX swauthor_namesite_unique ON /*_*/swauthor;
ALTER TABLE /*_*/swauthor
  CHANGE COLUMN swa_uri swa_uri_part varbinary(255) NOT NULL,
  CHANGE COLUMN swa_site swa_site int unsigned;
CREATE UNIQUE INDEX /*i*/swauthor_namesite_unique ON /*_*/swauthor (swa_site,swa_uri_part,swa_user_name);

The current abstract schema contains only two columns

UNIQUE INDEX swauthor_namesite_unique (swa_site, swa_user_name),

No idea what is on production.

Not sure if something was missed on creating the abstract schema, but the field swa_uri_part is not used in code (only similiar named column on other table srcwork_uri_part, that is also part of the unique index). The field was used by the maintenance script from the patch set above, but not outside of that.

You are right but at the same time, this table is completely unused. I don't know why it's in production even :/ Maybe we can drop these tables?

A bit of context: WikiVoyage was running running a very old MW version on postgres with a couple of custom extensions. There were a couple of Postgres-specific things that needed some refactoring before bringing to MySQL. Some extensions also shared tables, IIRC. CreditsSource was one of those extensions that were adopted when WikiVoyage was migrated to WMF and needed some tweaking.

Even in the original pre-migration extension code, swauthor was unused in code; only present in zsamm.sql
I'm going to assume that "zsamm" was some abbreviation of "zusammen" ("together" in German), so I'm guessing this particular table may have been in use in another extension.

The follow-up migration patch still makes no use of this table, other than in a maintenance script that migrates some data.
I think it's safe to say that this table is not in use in this extension & wasn't properly cleaned up (possibly because it was also in use in another extension, or out of an abundance of caution)

I combed through all other (remaining) WikiVoyage extensions and can't find swauthor remnants. CodeSearch also comes up blank.
I think it's safe to drop this table.

Thanks for the notes. We can drop it then.
