This patch is to add more comments
to postgres.init.sh , clairify the options
available, and to add easy support
for installation of postgres into the
runlevel system.
"sh postgres.init.sh install"
Will now install "postgres" in the
/etc/rc.d/init.d directory and execute
/sbin/chkconfig to hook up the symbolic
links. An uninstall option is also added.

Add 'temporary file' facility to fd.c, and arrange for temp
files to be closed automatically at transaction abort or commit, should
they still be open. Also close any still-open stdio files allocated with
AllocateFile at abort/commit. This should eliminate problems with leakage
of file descriptors after an error. Also, put in some primitive buffered-IO
support so that psort.c can use virtual files without severe performance
penalties.

Please apply the following patch for regress.sh to do something useful with
"SYSTEM", and unpack the files in the uuencoded .tar.gz file at the end in
src/test/regress so that the int2, int4 and geometry tests pass on NetBSD/i386.
They just fail on different wording of error messages and eg printing "0"
rather than "-0". At a guess the same will be true for the other NetBSD ports,
but I can't test them.

Fix some nasty coredump bugs in hashjoin. This code was just
about certain to fail anytime it decided the relation to be hashed was
too big to fit in memory --- the code for 'batching' a series of hashjoins
had multiple errors. I've fixed the easier problems. A remaining big
problem is that you can get 'hashtable out of memory' if the code's
guesstimate about how much overflow space it will need turns out wrong.
That will require much more extensive revisions to fix, so I'm committing
these fixes now before I start on that problem.
Use sprintf() to convert float8 to a string during conversion to numeric.
Original code used float8out(), but the resulting exponential notation
was not handled (e.g. '3E9' was decoded as '3').

here are some patches for 6.5.0 which I already submitted but have never
been applied. The patches are in the .tar.gz attachment at the end:
varchar-array.patch this patch adds support for arrays of bpchar() and
varchar(), which where always missing from postgres.
These datatypes can be used to replace the _char4,
_char8, etc., which were dropped some time ago.
block-size.patch this patch fixes many errors in the parser and other
program which happen with very large query statements
(> 8K) when using a page size larger than 8192.
This patch is needed if you want to submit queries
larger than 8K. Postgres supports tuples up to 32K
but you can't insert them because you can't submit
queries larger than 8K. My patch fixes this problem.
The patch also replaces all the occurrences of `8192'
and `1<<13' in the sources with the proper constants
defined in include files. You should now never find
8192 hardwired in C code, just to make code clearer.

It looks like the multibyte regress tests only work if both
the database encoding and the client encoding match the encoding expected
by the test. So, force both of them to be set from the MULTIBYTE
environment var. This allows regress tests to be run successfully in
multibyte environments other than the compiled-in default.

Fix kill() call in elog() so that it gets its own pid by calling getpid().
MyProcPid global variable is set to 0 when postgres starts as a command
(not as a backend daemon). This leads issuing SIGQUIT to the process group,
not the process itself. As a result, parent sh gets core dumped in the
Wisconsin benchmark test.

- change temp -> temp_bench ("temp" is now a reserved word)
- fix bugs in queries
- add -B 256 option to run the postgres command

Fix max(int8) result by making sure int8larger() copies its result

Also made the same fix to int8smaller(), though there wasn't a symptom,
and went through and verified that other pass-by-reference data types
do the same thing. Not an issue for the by-value types.
