Subject: [HACKERS] pgaccess Japanese input capability patch

Hi Teodorescu,

I have made patches which enable pgaccess to input Japanese characters
in the table editing window. As you might know, to input Japanese
characters, we first type in "hiragana" then convert it to "kanji". To
make this proccess transparent to tcl application programs, libraries
are provided with localized version of Tcl/Tk. The patches bind
certain keys to initiate a function (kanjiInput) that is responsible
for the conversion process. If the function is not available, those
keys will not be binded.

23 years agoImplement COMMIT_SIBLINGS parameter to allow pre-commit delay to occur
Tom Lane [Mon, 26 Feb 2001 00:50:08 +0000 (00:50 +0000)]
Implement COMMIT_SIBLINGS parameter to allow pre-commit delay to occur
only if at least N other backends currently have open transactions.  This
is not a great deal of intelligence about whether a delay might be
profitable ... but it beats no intelligence at all.  Note that the default
COMMIT_DELAY is still zero --- this new code does nothing unless that

Also, mark ENABLEFSYNC as a system-wide setting.  It's no longer safe to

23 years agoClean up two rather nasty bugs in operator selection code.
Tom Lane [Fri, 16 Feb 2001 03:16:58 +0000 (03:16 +0000)]
Clean up two rather nasty bugs in operator selection code.

1. If there is exactly one pg_operator entry of the right name and oprkind,
oper() and related routines would return that entry whether its input type
had anything to do with the request or not.  This is just premature
optimization: we shouldn't return the single candidate until after we verify
that it really is a valid candidate, ie, is at least coercion-compatible
with the given types.

2. oper() and related routines only promise a coercion-compatible result.
Unfortunately, there were quite a few callers that assumed the returned
operator is binary-compatible with the given datatype; they would proceed
to call it without making any datatype coercions.  These callers include
sorting, grouping, aggregation, and VACUUM ANALYZE.  In general I think
it is appropriate for these callers to require an exact or binary-compatible
match, so I've added a new routine compatible_oper() that only succeeds if
it can find an operator that doesn't require any run-time conversions.
Callers now call oper() or compatible_oper() depending on whether they are
prepared to deal with type conversion or not.

The upshot of these bugs is revealed by the following silliness in PL/Tcl's
selftest: it creates an operator @< on int4, and then tries to use it to
sort a char(N) column.  The system would let it do that :-( (and evidently
has done so since 6.3 :-( :-().  The result in this case was just a silly
sort order, but the reverse combination would've provoked coredump from
trying to dereference integers.  With this fix you get more reasonable
behavior:
pltcl_test=# select * from T_pkey1 order by key1, key2 using @<;
ERROR:  Unable to identify an operator '@<' for types 'bpchar' and 'bpchar'
        You will have to retype this query using an explicit cast
