Description michaelcirello2 2014-02-27 00:01:15 UTC 
Special pages (BrokenRedirects, etc) are generating invalid SQL.  It seems the 'from' and 'join' clauses are not being constructed correctly.  This is with Postgres as the db if it matters.  

Example query generated from brokenredirects below.  Note FROM "p2".  This obviously doesn't exist and was supposed to be part of a join that is not included at all.

SELECT /* BrokenRedirectsPage::reallyDoQuery Mike */  
        p1.page_namespace AS namespace,
        p1.page_title AS title,
        p1.page_title AS VALUE,
        rd_namespace,
        rd_title  
FROM "p2"  
WHERE (rd_namespace >= 0) AND
        (rd_interwiki IS NULL OR rd_interwiki = '') AND
        (p2.page_namespace IS NULL)  
ORDER BY rd_namespace,rd_title,rd_from
LIMIT 51  
FOR UPDATE OF p1

Yep it does. (How SQL is constructed is different for every db backend)
Comment 2 Sam Reed (reedy) 2014-02-27 00:08:27 UTC 
Testing this locally on 1.22.2 and using mysql seems to work fine. Highly suspect its an issue with the postgres wrapper class
Comment 3 Umherirrender 2014-02-27 20:01:57 UTC 
Sounds like the problem from bug 60031
Comment 4 db [inactive,noenotif] 2014-03-01 11:12:25 UTC 
Fixed in the meantime, should be part of 1.22.3 (Looks like bug 60531)
