Hm. I don't see a segfault from this. I do see the CREATE TEMP TABLE
command failing with "ctid is NULL", which probably shouldn't be happening
... but no segfault. I tried with current HEAD and with current 9.3
branch tip, so it's possible there's been some relevant bugfix since
9.3.5.

I think it's much more likely something to do with EvalPlanQual. There
have been some bugs fixed in that area since 9.3.5, but none of them
look real promising as an explanation for this ...
