pg_visibility: Restrict access to more relation types Temporary relations of other sessions have their own local pages. Temporary and unlogged relations have no storage during recovery. pg_visibility did not check for either cases, leading to inconsistent results or confusing error messages, like some "ERROR: could not open file".
This commit adds checks for both cases, so as a clean errors are returned instead of the previous mix of incorrect results or errors, depending on the function called and the relation whose information is requested.
