566c712c58 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.

qualification expression trees in the execution state. Prevents from
memory exhaustion on INSERT, UPDATE or COPY to tables that have CHECK

3982368a4e The libpq function PQfnumber does not handle case-insensitive 
comparisons correctly. The psql monitor converts all table and field
names to lower case. If the PQfnumber function is called with a mixed
case name, it will always return -1.

724119a979 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.

eb3415538e 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.

2163d9e33e Add missing mb files. 1999-02-02 19:04:43 +00:00
Bruce Momjian
a7ad43cd18 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)
