when user does another FETCH after reaching end of data, or another
FETCH backwards after reaching start.  This is needed because some plan
nodes are not very robust about being called again after they've already
returned NULL; for example, MergeJoin will crash in some states but not
others.  While the ideal approach would be for them all to handle this
correctly, it seems foolish to assume that no such bugs would creep in
again once cleaned up.  Therefore, the most robust answer is to prevent
the situation from arising at all.

noncachable, so that CURRENT_DATE and CURRENT_TIME work as functions
again, rather than being collapsed to constants immediately.  Marking the
reverse conversions noncachable might be overkill, but I'm not sure;
do these datatypes have the notion of a CURRENT value?  Better safe than
sorry, for now.

I kept the name as generic as possible though, as other OS should have
similar methods, so this can be extended "as appropriate" ...

vacuum analyze on pg_type fails if bogus entries remain in pg_operator.
Here is a sample script to reproduce the problem.

drop table t1;
create table t1(i int);
drop function foo(t1,t1);
create function foo(t1,t1) returns bool as 'select true' language 'sql';
create operator = (
	leftarg = t1,
	rightarg = t1,
	commutator = =,
	procedure = foo
	);
drop table t1;
vacuum analyze;

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.

Comments?

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
setting is changed.
Also, mark ENABLEFSYNC as a system-wide setting.  It's no longer safe to
allow that to be set per-backend, since we may be relying on some other
backend's fsync to have synced the WAL log.

does not lead to a one-second delay, but to an immediate EINVAL failure.
This causes CHECKPOINT to crash with s_lock_stuck much too quickly :-(.
Fix by breaking down the requested wait div/mod 1e6.

example.

proc_exit(1).  Unless you think a system-wide restart is an appropriate
response to bogus PGOPTIONS, that is.

on some platforms, which is not too surprising considering how platform
specific these macros must be).

version number from the current database, and couldn't find any existing
program to do that.

right.  We should MAXALIGN the individual items because we'll
allocate them individually, not as an array.

update to beta5 ... I think I ran cvs2cl right this time? :)
