Kind of doubt it. It'd bloat debug builds with a lot of redundant checks, and probably never catch anything. For catching problems in production, the right place to do this (and where we already do do it) is in _bt_checkpage. If any of the other AMs lack page-read-time sanity checks like _bt_checkpage, I'd be in favor of adding that. But I don't think a whole bunch of additional checks afterwards will buy much. regards, tom lane
