The functions bt_metap, bt_page_stats and bt_page_items had moved from contrib/pgstattuple to pageinspect. We've already fixed English documentation, but Japanese version does not catch up. ITAGAKI Takahiro

pgstattuple
-----------
Add index information to /contrib/pgstattuple: This is an extension of pgstattuple to query information from indexes. It supports btree, hash and gist. Gin is not supported. It scans only index pages and does not read corresponding heap tuples. Therefore, 'dead_tuple' means the number of tuples with LP_DELETE flag. Also, I added an experimental feature for btree indexes. It checks fragmentation factor of indexes. If an leaf has the right link on the next adjacent page in the file, it is assumed to be continuous (not fragmented). It will help us to decide when to REINDEX. ITAGAKI Takahiro

Fix pgstattuple to acquire a read lock on the target table. This
prevents embarassments such as having the table dropped or truncated
partway through the scan. Also, fix free space calculation to include
pages that currently contain no tuples.
