cleanup stage to finish incomplete inserts or splits anymore. There was two reasons for the cleanup step: 1. When a new tuple was inserted to a leaf page, the downlink in the parent needed to be updated to contain (ie. to be consistent with) the new key. Updating the parent in turn might require recursively updating the parent of the parent. We now handle that by updating the parent while traversing down the tree, so that when we insert the leaf tuple, all the parents are already consistent with the new key, and the tree is consistent at every step. 2. When a page is split, we need to insert the downlink for the new right page(s), and update the downlink for the original page to not include keys that moved to the right page(s). We now handle that by setting a new flag, F_FOLLOW_RIGHT, on the non-rightmost pages in the split. When that flag is set, scans always follow the rightlink, regardless of the NSN mechanism used to detect concurrent page splits. That way the tree is consistent right after split, even though the downlink is still missing. This is very similar to the way B-tree splits are handled. When the downlink is inserted in the parent, the flag is cleared. To keep the insertion algorithm simple, when an insertion sees an incomplete split, indicated by the F_FOLLOW_RIGHT flag, it finishes the split before doing anything else. These changes allow removing the whole "invalid tuple" mechanism, but I retained the scan code to still follow invalid tuples correctly. While we don't create any such tuples anymore, we want to handle them gracefully in case you pg_upgrade a GiST index that has them. If we encounter any on an insert, though, we just throw an error saying that you need to REINDEX. The issue that got me into doing this is that if you did a checkpoint while an insert or split was in progress, and the checkpoint finishes quickly so that there is no WAL record related to the insert between RedoRecPtr and the checkpoint record, recovery from that checkpoint would not know to finish the incomplete insert. IOW, we have the same issue we solved with the rm_safe_restartpoint mechanism during normal operation too. It's highly unlikely to happen in practice, and this fix is far too large to backpatch, so we're just going to live with in previous versions, but this refactoring fixes it going forward. With this patch, you don't get the annoying 'index "FOO" needs VACUUM or REINDEX to finish crash recovery' notices anymore if you crash at an unfortunate moment.

Version: 0.91 for PgSQL 6.5
Author: Pavel Behal
Revised by: Tatsuo Ishii
Email: behal@opf.slu.cz
Licence: The Same as PostgreSQL
Sorry for my Eglish and C code, I'm not native :-)
!!!!!!!!!!!!!!!!!!!!!!!!! NO WARRANTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Instalation:
------------
1) Change three affected files in source directories
(I don't have time to create proper patch diffs, I don't know how)
[PostgreSQL 6.5.1$B$G$O$3$N%9%F%C%W$OI,MW$"$j$^$;$s!%(B-- $B@P0f(B]
2) Compile with enabled locale and multibyte set to LATIN2
3) Setup properly your instalation, do not forget to create locale
variables in your profile (environment). Ex. (may not be exactly true):
LC_ALL=cs_CZ.ISO8859-2
LC_COLLATE=cs_CZ.ISO8859-2
LC_CTYPE=cs_CZ.ISO8859-2
LC_MONETARY=cs_CZ.ISO8859-2
LC_NUMERIC=cs_CZ.ISO8859-2
LC_TIME=cs_CZ.ISO8859-2
4) You have to start the postmaster with locales set!
5) Try it with Czech language, it have to sort
5) Install ODBC driver for PgSQL into your M$ Windows
6) Setup properly your data source. Include this line in your ODBC
configuration dialog in field "Connect Settings:" :
SET CLIENT_ENCODING = 'WIN1250';
7) Now try it again, but in Windows with ODBC.
Description:
------------
- Depends on proper system locales, tested with RH6.0 and Slackware 3.6,
with cs_CZ.iso8859-2 loacle
- Never try to set-up server multibyte database encoding to WIN1250,
always use LATIN2 instead. There is not WIN1250 locale in Unix
- WIN1250 encoding is useable only for M$W ODBC clients. The characters are
on thy fly re-coded, to be displayed and stored back properly
Important:
----------
- it reorders your sort order depending on your LC_... setting, so don't be
confused with regression tests, they don't use locale
- "ch" is corectly sorted only in some newer locales (Ex. RH6.0)
- you have to insert money as '162,50' (with comma in aphostrophes!)
- not tested properly
