Bruce Momjian	74924d29fa	Add functions to /contrib/pgstattuple that show index statistics and ... index page contents. Satoshi Nagayasu	20 years ago
Bruce Momjian	dab42382f4	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	20 years ago

Tom Lane	e4186762ff	Adjust nodeFunctionscan.c to reset transient memory context between calls ... to the table function, thus preventing memory leakage accumulation across calls.

Tom Lane	5f4745adf4	Further cleanups for relations in schemas: teach nextval and other ... sequence functions how to cope with qualified names. Same code is also used for int4notin, currtid_byrelname, pgstattuple. Also, move TOAST tables into special pg_toast namespace.	24 years ago
Tom Lane	897083715b	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.	24 years ago
