global variables are problematic on this platform. Simplest solution
seems to be to initialize pthread key variable to 0. Also, rename this
variable and check_sigpipe_handler to something involving "pq" to
avoid gratuitous pollution of application namespace.

OK, having no M$ diff, I attach files src\interfaces\libpq\bcc32.mak and
src\interfaces\libpq\win32.h

(.dylib format) on Mac OS X, while not messing up loadable modules for
the backend (which are the same kind of animal as a shared library on
every other platform, but not here). Also get the naming convention
to match OS X practice, viz libFOO.version.so not libFOO.so.version.
In support of that last, refactor code in Makefile.shlib to make it
easier to have platform-specific shlib naming conventions.
This patch is loosely based on the Fink project's current postgresql.patch.
Tested by yours truly on OS X 10.3.4; does anyone have 10.2.* to check
it on?

user must initialize the lock. The problem are concurrent "first" users
- the pthread_mutex_t initialization must be synchronized.
The current implementation is broken, the attached patches fixes that:
mutex_initlock is a spinlock. If the pthread_mutex_t mutex is not
initialized, then the spinlock is acquired, if the pthread_mutex_t is
initialized if it's not yet initialized and then the spinlock is
dropped.

Note that this still has some bugs. The functionality is there though, it's just a matter of fixing the bugs now.
Cleaned up error handling in preprocessor.
- Variables that are out of scope, were not removed all the time.
- Make a varchar NULL set everything to 0 when not using indicators.
- Synced parser.
extensive change then what was suggested. I found the file path.c that
contained a lot of "Unix/Windows" agnostic functions so I added a function
there instead and removed the PATHSEP declaration in exec.c altogether. All
to keep things from scattering all over the code.
I also took the liberty of changing the name of the functions
"first_path_sep" and "last_path_sep". Where I come from (and I'm apparently
not alone given the former macro name PATHSEP), they should be called
"first_dir_sep" and "last_dir_sep". The new function I introduced, that
actually finds path separators, is now the "first_path_sep". The patch
contains changes on all affected places of course.
I also changed the documentation on dynamic_library_path to reflect the
chagnes.

environment variable processing to libpq.
The patch also adds code to our client apps so we set the environment
variable directly based on our binary location, unless it is already
set. This will allow our applications to emit proper locale messages
that are generated in libpq.

patch-tmp-schema.txt contains the following bits:
*) Changes pg_namespace_aclmask() so that the superuser is always able
to create objects in the temp namespace.
*) Changes pg_namespace_aclmask() so that if this is a temp namespace,
objects are only allowed to be created in the temp namespace if the
user has TEMP privs on the database. This encompasses all object
creation, not just TEMP tables.
*) InitTempTableNamespace() checks to see if the current user, not the
session user, has access to create a temp namespace.
The first two changes are necessary to support the third change. Now
it's possible to revoke all temp table privs from non-super users and
limiting all creation of temp tables/schemas via a function that's
executed with elevated privs (security definer). Before this change,
it was not possible to have a setuid function to create a temp
table/schema if the session user had no TEMP privs.
patch-area-path.txt contains:
*) Can now determine the area of a closed path.
patch-dfmgr.txt contains:
*) Small tweak to add the library path that's being expanded.
I was using $lib/foo.so and couldn't easily figure out what the error
message, "invalid macro name in dynamic library path" meant without
looking through the source code. With the path in there, at least I
know where to start looking in my config file.

It was necessary to touch in grammar and create a new node to make home
to the new syntax. The command is also supported in E
CPG. Doc updates are attached too. Only superusers can change the owner
of the database. New owners don't need any aditional
privileges.
