Fix handling of non-upgraded B-tree metapages 857f9c36 bumps B-tree metapage version while upgrade is performed "on the fly" when needed. However, some asserts fired when old version metapage was cached to rel->rd_amcache. Despite new metadata fields are never used from rel->rd_amcache, that needs to be fixed. This patch introduces metadata upgrade during its caching, which fills unavailable fields with their default values. contrib/pageinspect is also patched to handle non-upgraded metapages in the same way.
