be able to apply against what you just committed. It rolls soundex into
fuzzystrmatch.
Remove soundex/metaphone and merge into fuzzystrmatch.

Here is a context diff from latest cvs
And I see why you couldn't apply the last diff, the setCatalog diff has
been backed out, that was causing the compile problem in the first
place.
This following one needs to be applied to allow the current cvs to
compile

metaphone() in a contrib. There seem to be a fair number of different
approaches to both of these algorithms. I used the simplest case for
levenshtein which has a cost of 1 for any character insertion, deletion, or
substitution. For metaphone, I adapted the same code from CPAN that the PHP
folks did.
A couple of questions:
1. Does it make sense to fold the soundex contrib together with this one?
2. I was debating trying to add multibyte support to levenshtein (it would
make no sense at all for metaphone), but a quick search through the contrib
directory found no hits on the word MULTIBYTE. Should worry about adding
multibyte support to levenshtein()?

clauses are equal(), before trying to match them up using btree opclass
inference rules. This allows it to recognize many simple cases involving
non-btree operations, for example 'x IS NULL'. Clean up code a little.
Make sure it exits immediately when collector process dies --- in old code,
buffer process would hang around and compete with the new buffer process
for packets. Make sure it doesn't block on writing the pipe when the
collector falls more than a pipeload behind. Avoid leaking pgstats FDs
into every backend.

The Debian bug report says, "The upstream source makes use of NOFILE
unconditionalized. As the Hurd doesn't have an arbitrary limit on the
number of open files, this is not defined. But _SC_OPEN_MAX works fine
and returns 1024 (applications can increase this as they want), so I
suggest the below diff. Please forward this upstream, too."

* The ability to index more than one column in a table with a single
trigger.
* All uses of sprintf changed to snprintf to prevent users from crashing
Postgres.
* Error messages made more consistent
* Some changes made to bring it into line with coding requirements for
triggers specified in the docs. (ie. check you're a trigger before casting
your context)
* The perl script that generate indices has been updated to support indexing
multiple columns in a table.
* Fairly well tested in our development environment indexing a food
database's brand and description fields. The size of the fti index is
around 300,000 rows.
* All docs and examples upgraded. This includes specifying more efficient
index usage that was specified before, better examples that don't produce
duplicates, etc.

1) improves performance of commit/rollback by reducing number of round
trips to the server
2) uses 7.1 functionality for setting the transaction isolation level
3) backs out a patch from 11 days ago because that code failed to
compile under jdk1.1
Details:
1) The old code was doing the following for each commit:
commit
begin
set transaction isolation level xxx
thus a call to commit was performing three round trips to the database.
The new code does this in one round trip as:
commit; begin; set transaction isolation level xxx
In a simple test program that performs 1000 transactions (where each
transaction does one simple select inside that transaction) has the
following before and after timings:
Client and Server on same machine
old new
--- ---
1.877sec 1.405sec 25.1% improvement
Client and Server on different machines
old new
--- ---
4.184sec 2.927sec 34.3% improvement
(all timings are an average of four different runs)
2) The driver was using 'set transaction isolation level xxx' at the
begining of each transaction, instead of using the new 7.1 syntax of
'set session characteristics as transaction isolation level xxx' which
only needs to be done once instead of for each transaction. This is
done conditionally (i.e. if server is 7.0 or older do the old behaviour,
else do the new behaviour) to not break backward compatibility. This
also required the movement of some code to check/test database version
numbers from the DatabaseMetaData object to the Connection object.
3) Finally while testing, I discovered that the code that was checked in
11 days ago actually didn't compile. The code in the patch for
Connection.setCatalog() used Properties.setProperty() which only exists
in JDK1.2 or higher. Thus compiling the JDBC1 driver failed as this
method doesn't exist. Thus I backed out that patch.

platforms system(2) gets confused unless the signal handler is set to
SIG_DFL, not SIG_IGN. pgstats.c now uses pqsignal() as it should,
not signal(). Also, arrange for the stats collector process to show
a reasonable ID in 'ps', rather than looking like a postmaster.
Dump the alignment and storage information for user-defined types (how'd
that manage to slip through the cracks?), and don't dump 'shell' types
that don't have typisdefined set. Fix badly broken logic for dependencies
of type definitions (did not work for more than one user-defined type...).
Avoid memory leakage within pg_dump by being more careful to release
storage used by PQExpBuffer objects.
exec_eval_simple_expr shortcut, which was diked out in 7.1 because it
leaked too much space. CVS tip now leaks no memory in Chris Ruprecht's
example, which formerly leaked to the tune of 500 MB. (Much of this
is work that Jan already did; this commit just cleans up around the
edges.)
Sorry I don't have the original around to make a quick diff, but its a very small change... I think this should be in the next release, there's no reason not to have it.
its a function with no expected arguments, so you can use it like:
spi_exec "INSERT INTO mytable(columns...) VALUES(values..)"
set oid [spi_lastoid]
spi_exec "SELECT mytable_id from mytable WHERE oid=$oid"
It just didn't make sense for me to use plpgsql and pltcl, or just screw
them both and use SPI from C.

that call is not needed to prepare for SO_PEERCRED. Also, simplify code
so that #ifdef SO_PEERCRED appears in only one place, to make it easier
to support other platforms with variants of this capability.
points out how silly it is to use Autoconf to test for a preprocessor
symbol, when one can equally easily #ifdef on the symbol itself.
Accordingly, revert configure to prior state and do it that way.
system supports SO_PEERCRED requests for Unix sockets. This is an
amalgamation of patches submitted by Helge Bahmann and Oliver Elphick,
with some editorializing by yours truly.

TIOCGWINSZ is defined as follows:
Linux asm/ioctls.h
FreeBSD sys/ttycom.h. This file is included by sys/ioctl.h.
Solaris sys/termios.h
This patch tells print.c to know TIOCGWINSZ on Solaris platform. Same code is
founded in src/bin/psal/common.c.

substrings of two characters or greater, and is case-sensitive.
This patch makes it work correctly. It generates only the suffixes of each
word, plus lowercases them - as specified by the README file.
This brings it into line with the fti.c function, makes it case-insensitive
properly, removes the problem with duplicate rows being returned from an fti
search and greatly reduces the size of the generated index table.
It was written by my co-worker, Brett Toolin.
