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.

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,

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)

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

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().

e27f8791f9 Turns out it's easy to cache the fmgr function lookup 
result, too ... another little bit of speed for SELECT.
 1999-01-27 01:11:43 +00:00
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 ...

443e24beb7 Tighten coding of fmgr_isbuiltin() ... managed to speed it up 
by about 10% which seems to be good for half a percent or so of a SELECT.

49b6be244c Tighten coding of inner loops in nocachegetattr ...

18577547d4 Use heap_attisnull, rather than heap_getattr, for a small 
but useful speedup.

d03e98737c Replace typtoout() and gettypelem() with a single routine, 
so that fetching an attribute value needs only one SearchSysCacheTuple call
instead of two redundant searches.  This speeds up a large SELECT by about
ten percent, and probably will help GROUP BY and SELECT DISTINCT too.

157349e3af Improper addition of NaN/Infinity recognition to float8in() 
was causing it not to detect out-of-range float values, as evidenced by
failure of float8 regression test.  I corrected that logic and also
modified expected float8 results to account for new error message
generated for out-of-range inputs.
