Bruce Momjian 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.

Tom Lane 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.

Bruce Momjian f1b7823471 Make GEQO use dependent on table and index count. 1999-02-02 20:30:18 +00:00
Bruce Momjian 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.

        regards,

Bruce Momjian 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)

The following patch does two things.

 - Clarifies what the effect of allowing users to add new users (Thet
   become super-users.)
 - Makes the default database for the new user if they are not allowed
   to and the user agrees to create it.

(due to concurrent update) from one initially produced by top level plan.

Left are identifiers that contain non-alnum/_ chars.

Marc G. Fournier 2ae5d51668 From: Tatsuo Ishii <t-ishii@sra.co.jp>
Included patches fix a portability problem of unsetenv() used in
6.4.2 multi-byte support. unsetenv() is only avaliable on FreeBSD and
Linux so I decided to replace with putenv().

Tom Lane e27f8791f9 Turns out it's easy to cache the fmgr function lookup
result, too ... another little bit of speed for SELECT.

Tom Lane 422221c90d Another SELECT speedup: extract OIDs of column print functions
only once per SELECT, not once per tuple.  10% here, 10% there,
pretty soon you're talking about real speedups ...
