Log Message: ----------- 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.
