Query error: 1054 Unknown column 'Array' in 'where clause' (ApiStashEdit::checkCache)

[kghbln]

On about every second edit of the [annotation health](https://wikiapiary.com/wiki/Semantic_statistics/Annotation_Health page) I get this error message. To save the page I have to do a trivial change between the first and last char of wikitext.

A database query error has occurred. This may indicate a bug in the software.

    Query:
    SELECT 1 FROM `page` WHERE (Array) OR (Array) OR (Array) LIMIT 1
    Function: ApiStashEdit::checkCache
    Error: 1054 Unknown column 'Array' in 'where clause' (db-local)

@thingles I guess it will be nice to have a stack trace for this.

That's a new variant:

    Query:
    SELECT 1 FROM `page` WHERE (Array) LIMIT 1
    Function: ApiStashEdit::checkCache
    Error: 1054 Unknown column 'Array' in 'where clause' (db-local)

[0] give some hints as to what ApiStashEdit actually does (apparently you can disable it [1]) and it seems someone made a 1.25 backport [2].

Thanks a ton for the info! Apparently not backported to the MW 1.25.x branch. One of MW's finest hours?

Ah, no. This was one of my finest moments. The backport was not referenced to the issue and I forgot about [2] the moment I hit save. :(

Closing now with upgrade to 1.25.3.
