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.

a0ffab351e Magic blocks don't do us any good unless we use 'em ... so install one
in every shared library.

978129f28e Document get_call_result_type() and friends; mark TypeGetTupleDesc()
and RelationNameGetTupleDesc() as deprecated; remove uses of the
latter in the contrib library.  Along the way, clean up crosstab()
code and documentation a little.

9ffc8ed58b Repair possible failure to update hint bits back to disk, per
http://archives.postgresql.org/pgsql-hackers/2004-10/msg00464.php.
This fix is intended to be permanent: it moves the responsibility for
calling SetBufferCommitInfoNeedsSave() into the tqual.c routines,
eliminating the requirement for callers to test whether t_infomask changed.
Also, tighten validity checking on buffer IDs in bufmgr.c --- several
routines were paranoid about out-of-range shared buffer numbers but not
about out-of-range local ones, which seems a tad pointless.

4af3421161 Get rid of rd_nblocks field in relcache entries. Turns out this was
costing us lots more to maintain than it was worth.  On shared tables
it was of exactly zero benefit because we couldn't trust it to be
up to date.  On temp tables it sometimes saved an lseek, but not often
enough to be worth getting excited about.  And the real problem was that
we forced an lseek on every relcache flush in order to update the field.
So all in all it seems best to lose the complexity.

375369acd1 Replace TupleTableSlot convention for whole-row variables and function
results with tuples as ordinary varlena Datums.  This commit does not
in itself do much for us, except eliminate the horrid memory leak
associated with evaluation of whole-row variables.  However, it lays the
groundwork for allowing composite types as table columns, and perhaps
some other useful features as well.  Per my proposal of a few days ago.

a647e30ba3 New patch with corrected README attached.
Also quickly added mention that it may be a qualified schema name.

e4186762ff Adjust nodeFunctionscan.c to reset transient memory context between calls
to the table function, thus preventing memory leakage accumulation across
calls.  This means that SRFs need to be careful to distinguish permanent
and local storage; adjust code and documentation accordingly.  Patch by
Joe Conway, very minor tweaks by Tom Lane.

44fbe20d62 Restructure indexscan API (index_beginscan, index_getnext) per
yesterday's proposal to pghackers.  Also remove unnecessary parameters
to heap_beginscan, heap_rescan.  I modified pg_proc.h to reflect the
new numbers of parameters for the AM interface routines, but did not
force an initdb because nothing actually looks at those fields.

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.

92288a1cf9 Change made to elog:
o  Change all current CVS messages of NOTICE to WARNING.  We were going
to do this just before 7.3 beta but it has to be done now, as you will
see below.

o Change current INFO messages that should be controlled by
client_min_messages to NOTICE.

o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc.
to always go to the client.

o Remove INFO from the client_min_messages options and add NOTICE.

Seems we do need three non-ERROR elog levels to handle the various
behaviors we need for these messages.

Regression passed.

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.
