These functions have been marked parallel safe, but the buildfarm's response to commit e2933a6e1 exposed the flaw in that thinking: if you try to use them on a temporary table, and they run inside a parallel worker, they'll fail with "cannot access temporary tables during a parallel operation". Fix that by marking them parallel restricted instead. Maybe someday we'll have a better answer and can reverse this decision. Back-patch to v15. To go back further, we'd have to devise variant versions of pre-1.10 pageinspect versions. Given the lack of field complaints, it doesn't seem worth the trouble. We'll just deem this case unsupported pre-v15. (If anyone does complain, it might be good enough to update the markings manually in their DBs.)
