The pg_trgm contrib module provides functions and index classes
for determining the similarity of text based on trigram
matching.
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.
conversion of basic ASCII letters. Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.
1. Fixed bug where sequences were being mirrored incorrectly if they
exceeded 127
2. Fixed a bug in the perl script with mirroring sequences(John
Burtenshaw sent an email to patches describing the bug in March but I
htink he forgot to attach his patch)
3. The dates/times in the transaction files will always use 2 digits.

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.

patch resolved) a new bug was uncovered when running with a debug level
of greater than 1.
This patch resolves this new found bug and fixes some of the other
debugging output to be more consistent.

script for Mac OS X. I added calls to utilize the bundled apache
rotatelogs script in the DB startup for log rotation. Also modified
startup parameters file to allow using the "SystemStarter" utility to
start/stop/restart postgres with a rotating log file.
The script credits David Wheeler, 2002. I wrote him a message about
the changes an he suggested I post them here. I explain some of the
changes below.
Not sure how to submit the changes. I have 3 files, "PostgreSQL"
script, "StartupParameters.plist" file, "pg_startupscript.diff" file.
The diff file was run against the original "PostgreSQL" script file.
I'll try attaching them to this message. If they get filtered I can
resend if needed.
Thanks.

------------------------------------
1) Changed the "Provides" parameter in StartupParameters.plist to
"PostgreSQL" from "postgres database" simply for ease of typing. It
seems that the SystemStarter utility uses the "Provides" value if you
want to control the script. This way I did not have to enclose it in
quotes on commandline. The modified StartupParameters.plist is now an
XML document also.
2) For the startup script I added 2 user modifiable variables:
# do you want to rotate the log files, 1=true 0=false
ROTATELOGS=1
# logfile rotate in seconds
ROTATESEC="604800"
I also added a non modifiable variable:
# The apache log rotation utility
LOGUTIL="/usr/sbin/rotatelogs"
I modified the StartService and RestartService functions to execute
the new commands if the user wants log rotation.

I have changed the name of the new parse function to xml_valid and fixed
a reference to SortMem which meant that the code as supplied would work
against 7.3 and 7.4 but wouldn't work in CVS.
and, dblink_fetch -- allows ERROR on remote side of connection to
throw NOTICE locally instead of ERROR. Also removed documentation for
previously deprecated, now removed, functions.
have been able to significantly improve the contrib/xml XPath
integration code.
New features:
* XPath set-returning function allows multiple results from an several
XPath queries to be used as a virtual table.
* Using libxslt, XSLT transformations (with and without parameters) are
supported. (Caution: This support allows generic URL fetching from
within the backend as well).
I've removed the old code so that it is all libxml based. Rather than
attach as a patch, I've put the tar.gz (10k!) at
http://www.azuli.co.uk/pgxml-1.0.tar.gz
(all files in archive are xml/....).
I think this is worth replacing the contrib version with, even though
the function names have changed (though the same functionality is
there), because it includes a SRF and some SPI usage, in addition to
linking to an external library. And it isn't a big module! Obviously, I
understand that people might prefer to move it elsewhere, or might have
reservations about replacing an existing contrib module with an
incompatible one. I'm open to suggestions.

exposed thereby. AFAICT these would not lead to any worse problems than
junk emitted on the backend's stdout, but we should have the option to
catch possible worse errors in future.
with ReturnSetInfo->expectedDesc. This allows custom datatypes
(e.g. from tsearch2) to be returned at runtime. Previous behavior
depended on the type oid to match between the remote and local
database, which obviously doesn't work well for custom types.
Per report from Mark Gibson.
and FreeDir routines modeled on the existing AllocateFile/FreeFile.
Like the latter, these routines will avoid failing on EMFILE/ENFILE
conditions whenever possible, and will prevent leakage of directory
descriptors if an elog() occurs while one is open.
Also, reduce PANIC to ERROR in MoveOfflineLogs() --- this is not
critical code and there is no reason to force a DB restart on failure.
All per recent trouble report from Olivier Hubaut.

This update to dbmirror provides:
-replication of sequence operations via setval/nextval
-DBMirror.pl support for logging to syslog
-changed the names of the tables to dbmirror_* (no quotes required)
-Support for writitng SQL statements to files instead of directly to
a slave database
-More options for DBMirror.pl in the config files.

Make btree index creation and initial validation of foreign-key constraints
use maintenance_work_mem rather than work_mem as their memory limit.
Add some code to guc.c to allow these variables to be referenced by their
old names in SHOW and SET commands, for backwards compatibility.
pg_autovacuum looses track of any table that's ever been truncated
(possibly other situations too). When i truncate a table it gets a
new relfilenode in pg_class. This is a problem because pg_autovacuum
assumes pg_class.relfilenode will join to pg_stats_all_tables.relid.
pg_stats_all_tables.relid is actallly the oid from pg_class, not the
relfilenode. These two values start out equal so pg_autovacuum works
initially, but it fails later on because of this incorrect assumption.
This patch fixes that problem. Applied to HEAD and 7.4.X.

not initialized if a log file is not specified on the command line. This
causes an immediate segfault on systems that fill allocated memory with some
value other than zero (my FreeBSD machine uses 0xD0).
Several crashes later I discovered that args->user, password, host, and port
are also used without being initialized.
This doesn't appear to be fixed in CVS and I came up empty on a mailing list
search -- hope it hasn't been reported already.

pghackers proposal of 8-Nov. All the existing cross-type comparison
operators (int2/int4/int8 and float4/float8) have appropriate support.
The original proposal of storing the right-hand-side datatype as part of
the primary key for pg_amop and pg_amproc got modified a bit in the event;
it is easier to store zero as the 'default' case and only store a nonzero
when the operator is actually cross-type. Along the way, remove the
long-since-defunct bigbox_ops operator class.
Remove the 'strategy map' code, which was a large amount of mechanism
that no longer had any use except reverse-mapping from procedure OID to
strategy number. Passing the strategy number to the index AM in the
first place is simpler and faster.
This is a preliminary step in planned support for cross-datatype index
operations. I'm committing it now since the ScanKeyEntryInitialize()
API change touches quite a lot of files, and I want to commit those
changes before the tree drifts under me.
-References to older versions of PostgreSQL have been removed(It no
longer
compiles against older versions)
-Added a link to PgPerl at GBorg.

areas are for the lifetime of the backend and in the interests of not breaking
something that's not broken I left alone.
Note for anyone reading this and wanting it for tsearch-v2-stable (i.e. for 7.3
backend) this patch probably will not apply cleanly to that source. It should
be simple enough to see what's going on and apply the changes by hand if need
be.

The 'word' variable there is initialised from
the prs->words array, but immediately after,
that array may be reallocated, thus leaving
word pointing to unallocated memory.
