analyzejoins.c took care to clean out removed relids from the clause_relids and required_relids of RestrictInfos associated with the doomed rel ... but it paid no attention to the fact that if such a RestrictInfo contains an OR clause, there will be sub-RestrictInfos containing similar fields. I'm more than a bit surprised that this oversight hasn't caused visible problems before. In any case, it's certainly broken now, so add logic to clean out the sub-RestrictInfos recursively. We might need to back-patch this someday. Per bug #17786 from Robins Tharakan. Discussion: https://postgr.es/m/17786-f1ea7fbdab97daec@postgresql.org
