pg_plan_advice: Add CHECK_FOR_INTERRUPTS() and check_stack_depth() Without CHECK_FOR_INTERRUPTS(), backends might not respond to query cancellations in a timely fashion, especially for JOIN_ORDER() specifications, where matching against each join can take O(n^2) time in the length of the join order list in degenerate cases.
Recursive functions should check_stack_depth().
