Comment (by pramsey):

 We support 9.4 on 2.5?

 Anyways, the errors are the ones coming from trying to reconcile the
 different behaviour of CTEs between 12 and pre-12, since as of 12 we are
 now seeing the optimizer peeking into the CTE and pulling stuff out,
 whereas before that didn't happen. I pulled those tests apart and put the
 CTE stuff into subqueries to try and get equivalent behaviour which seems
 to have mostly worked. This commit tagged doesn't seem to have anything to
 do w/ the problem you are reporting here...
