From: Tom Lane <tgl@sss.pgh.pa.us>
Attached is a patch for this weekend's work on libpq. I've dealt
with several issues:
<for details: see message, in pgsql-patches archive for above data>
couple weeks ago on the hackers and interfaces lists:
1. When the backend sends a NOTICE message and closes the connection
(typically, because it was told to by the postmaster after
another backend coredumped), libpq will now print the notice
and close the connection cleanly. Formerly, the frontend app
would usually terminate ungracefully due to a SIGPIPE. (I am
not sure if 6.3.2 behaved that way, but the current cvs sources
do...)
2. libpq's various printouts to stderr are now fed through a single
"notice processor" routine, which can be overridden by the
application to direct notices someplace else. This should ease
porting libpq to Windows.
I also noticed and fixed a problem in PQprint: when sending output
to a pager subprocess, it would disable SIGPIPE in case the pager
terminates early (this is good) --- but afterwards it reset SIGPIPE
to SIG_DFL, rather than restoring the application's prior setting
(bad).

As Bruce mentioned, this is due to the conflict among changes we made.
Included patches should fix the problem(I changed all MB to
MULTIBYTE). Please let me know if you have further problem.
P.S. I did not include pathces to configure and gram.c to save the
file size(configure.in and gram.y modified).
Through some minor changes, I have been able to compile the libpq
client libraries on the Win32 platform. Since the libpq communications
part has been rewritten, this has become much easier. Enclosed is
a patch that will allow at least Microsoft Visual C++ to compile
libpq into both a static and a dynamic library. I will take a look
at porting the psql frontend as well, but I figured it was a good
idea to send in these patches first - so no major changes are done
to the files before it gets applied (if it does).

I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:
SET CLIENT_ENCODING TO 'encoding';
Other features include:
Latin1 support more 8 bit cleaness
See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.
