and for other compilers, insert a dummy exit() call so that they understand
PG_RE_THROW() doesn't return. Insert fflush(stderr) in ExceptionalCondition,
per recent buildfarm evidence that that might not happen automatically on some
platforms. And const-ify ExceptionalCondition's declaration while at it.
isn't any place to throw the error to. If so, we should treat the error
as FATAL, just as we would have if it'd been thrown outside the PG_TRY
block to begin with.
Although this is clearly a *potential* source of bugs, it is not clear
at the moment whether it is an *actual* source of bugs; there may not
presently be any PG_TRY blocks in code that can be reached with no outer
longjmp catcher. So for the moment I'm going to be conservative and not
back-patch this. The change breaks ABI for users of PG_RE_THROW and hence
might create compatibility problems for loadable modules, so we should not
put it into released branches without proof that it's needed.
log_min_messages does; and arrange to suppress the duplicative output
that would otherwise result from log_statement and log_duration messages.

the facility has been set, the facility gets set to LOCAL0 and cannot
be changed later. This seems reasonably plausible to happen, particularly
at higher debug log levels, though I am not certain it explains Han Holl's
recent report. Easiest fix is to teach the code how to change the value
on-the-fly, which is nicer anyway. I made the settings PGC_SIGHUP to
conform with log_destination.
These contain the SQLSTATE and error message of the current exception,
respectively. They are scope-local variables that are only defined
in exception handlers (so attempting to reference them outside an
exception handler is an error). Update the regression tests and the
documentation.
Also, do some minor related cleanup: export an unpack_sql_state()
function from the backend and use it to unpack a SQLSTATE into a
string, and add a free_var() function to pl_exec.c

Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...
elog() emulation code always calls errstart with ERROR error level.
This means that a recursive error call triggered by elog would do
MemoryContextReset(ErrorContext), whether or not this was actually
appropriate. I'm surprised we haven't seen this in the field...
recommend that people go get Apache's rotatelogs program. Additional
benefits are that configuration is done through GUC, rather than
externally, and that the postmaster can monitor the log rotator and
restart it after failure (though we certainly hope that won't happen
often).

more nearly Oracle-equivalent. Allow matching by category as well as
specific error code. Document the set of available condition names
(or more accurately, synchronize it with the existing documentation). In
passing, update errcodes.sgml to include codes added during 7.5 development.
possible to trap an error inside a function rather than letting it
propagate out to PostgresMain. You still have to use AbortCurrentTransaction
to clean up, but at least the error handling itself will cooperate.

Win32 port is now called 'win32' rather than 'win'
add -lwsock32 on Win32
make gethostname() be only used when kerberos4 is enabled
use /port/getopt.c
new /port/opendir.c routines
disable GUC unix_socket_group on Win32
convert some keywords.c symbols to KEYWORD_P to prevent conflict
create new FCNTL_NONBLOCK macro to turn off socket blocking
create new /include/port.h file that has /port prototypes, move
out of c.h
new /include/port/win32_include dir to hold missing include files
work around ERROR being defined in Win32 includes
rewritten and the protocol is changed, but most elog calls are still
elog calls. Also, we need to contemplate mechanisms for controlling
all this functionality --- eg, how much stuff should appear in the
postmaster log? And what API should libpq expose for it?
