- Replace sorted array of entries in maintenance_work_mem to binary tree,
this should improve create performance.
- More precisely calculate allocated memory, eliminate leaks
with user-defined extractValue()
- Improve wordings in tsearch2
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.

I finally found some time to debug this, and I think I found a better
patch than the one you proposed. Mine is still hackish and is still a
workaround around a proper quoting solution, but at least it repairs
the parsing without introducing the \' quoting again.
I consider this a band-aid patch to fix the recent security update.
PostgreSQL gurus, would you consider applying this until a better
solution is found for DBMirror.pl?
Olivier, can you please confirm that the patch works for you, too?
Backpatched to 8.0.X.

* new split algorithm (as proposed in http://archives.postgresql.org/pgsql-hackers/2006-06/msg00254.php)
* possible call pickSplit() for second and below columns
* add spl_(l|r)datum_exists to GIST_SPLITVEC -
pickSplit should check its values to use already defined
spl_(l|r)datum for splitting. pickSplit should set
spl_(l|r)datum_exists to 'false' (if they was 'true') to
signal to caller about using spl_(l|r)datum.
* support for old pickSplit(): not very optimal
but correct split
* remove 'bytes' field from GISTENTRY: in any case size of
value is defined by it's type.
* split GIST_SPLITVEC to two structures: one for using in picksplit
and second - for internal use.
* some code refactoring
* support of subsplit to rtree opclasses
TODO: add support of subsplit to contrib modules
tuples with less header overhead than a regular HeapTuple, per my
recent proposal. Teach TupleTableSlot code how to deal with these.
As proof of concept, change tuplestore.c to store MinimalTuples instead
of HeapTuples. Future patches will expand the concept to other places
where it is useful.
initially be 0. This is needed as a previous ABORT might have wiped out
an automatically opened transaction without maintaining the cursor count.
- Fix regression test expected file for the correct ERROR message, which
we now get given the above bug fix.
used by OpenOffice. Dictionaries are placed at
http://lingucomponent.openoffice.org/spell_dic.html
Dictionary automatically recognizes format of files.
Warning. MySpell's format has limitation with compound
word support: it's impossible to mark affix as
compound-only affix. So for norwegian, german etc
languages it's recommended to use original ispell format.
For that reason I don't want to remove my2ispell
scripts, it's has workaround at least for norwegian language.
It required some changes in lexize algorithm, but interface with
dictionaries stays compatible with old dictionaries.

should be no conflict. But ofcourse, if someone upgrades OpenSSL,
server starts crashing.

any use in the past many years, we'd have made some effort to include
them in all executor node types; but in fact they were only in
nodeAppend.c and nodeIndexscan.c, up until I copied nodeIndexscan.c's
occurrence into the new bitmap node types. Remove some other unused
macros in execdebug.h, too. Some day the whole header probably ought to
go away in favor of better-designed facilities.
pg_freespacemap_relations --- while one could theoretically get that
number by counting rows in pg_freespacemap_pages, it's surely the hard
way to do it. Avoid expensive and inconvenient conversion to and from
text format. Minor code and docs cleanup.
tracks index pages, not free space on pages):
1/ Index free bytes set to NULL
2/ Comment added to the README briefly mentioning the index business
3/ Columns reordered more logically
4/ 'Blockid' column removed
5/ Free bytes column renamed to just 'bytes' instead of 'blockfreebytes'
