Revert some changes from the INTERSECT/EXPECT patch that broke
...
rule system semantics by having Var nodes referenced across multiple
parsetrees when rules split them.
Added more tests to the rules regression test.
The code in question resulted from v6.3 based development and was
a little careless applied to the v6.5 source tree.

Changed ExecConstraints() and ExecRelCheck() to cache the constraints

qualification expression trees in the execution state. Prevents from
memory exhaustion on INSERT, UPDATE or COPY to tables that have CHECK
constraints. Speedup against the variant using freeObject() is more than
factor 2.

Modify int8 to not depend on sscanf(), and fix configure's test
...
for int8 support. configure now checks only snprintf() for int8 support,
not sprintf and sscanf as it used to. The reason for doing this is that
if we are supplying our own snprintf code (which does handle long long int),
we now only need working long long support in the compiler not in the
platform's C library. I have verified that int8 now passes regression test
on HPUX 9, and I think it should work on SunOS 4.1.* and other older
platforms if gcc is used.

OK I found it,
...
I search in the planner for the '\xFF' appending.
Finally I found in MakeIndexable() in gram.y
Attach a patch which removes the "<=" test in USE_LOCALE,
might make some queries a bit slower for us "locale-heads",
BUT correct result is more important.

Included patches make some enhancements to the multi-byte support.
...
o allow to use Big5 (a Chinese encoding used in Taiwan) as a client
encoding. In this case the server side encoding should be EUC_TW
o add EUC_TW and Big5 test cases to the regression and the mb test
(contributed by Jonah Kuo)
o fix mistake in include/mb/pg_wchar.h. An encoding id for EUC_TW was
not correct (was 3 and now is 4)
o update documents (doc/README.mb and README.mb.jp)
o update psql helpfile (bin/psql/psqlHelp.h)
