Tom Lane 97431d6739 Add some recursion and looping defenses in prepjointree.c. ... Andrey Lepikhov demonstrated a case where we spend an unreasonable amount of time in pull_up_subqueries(). Not only is that recursing with no explicit check for stack overrun, but the code seems not interruptable by control-C. Let's stick a CHECK_FOR_INTERRUPTS there, along with sprinkling some stack depth checks. An actual fix for the excessive time consumption seems a bit risky to back-patch; but this isn't, so let's do so.
