Making PQrequestCancel safe to call in a signal handler turned out to be
much easier than I feared. So here are the diffs.
Some notes:
* I modified the postmaster's packet "iodone" callback interface to allow
the callback routine to return a continue-or-drop-connection return
code; this was necessary to allow the connection to be closed after
receiving a Cancel, rather than proceeding to launch a new backend...
Being a neatnik, I also made the iodone proc have a typechecked
parameter list.
* I deleted all code I could find that had to do with OOB.
* I made some edits to ensure that all signals mentioned in the code
are referred to symbolically not by numbers ("SIGUSR2" not "2").
I think Bruce may have already done at least some of the same edits;
I hope that merging these patches is not too painful.
Used in the generic "CREATE xxx" parsing.
Do some automatic type conversion for inserts from other columns.
Previous trouble with "resjunk" regression test remains for now.
As mentioned around line 1153 in backend/commands/copy.c, the method
of array checking is not perfect.
test=> create table t1 (i text);
test=> insert into t1 values('{\\.}');
INSERT 2645600 1
test=> select * from t1;
i
-----
{\\.}
(2 rows)
test=> copy t1 to '/tmp/aaa';
test=> copy t1 from '/tmp/aaa';
ERROR: CopyReadAttribute - end of record marker corrupted
Copy cannot read data produced by itself!
I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:
SET CLIENT_ENCODING TO 'encoding';
Other features include:
Latin1 support more 8 bit cleaness
See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.

This incorporates all the precedeing patches and emailed suggestions
and the results of the performance testing I posted last week. I
would like to get this tested on as many platforms as possible so
I can verify it went in correctly (as opposed to the horrorshow
last time I sent in a patch).
Once this is confirmed, I will make a tarball of files that can be
dropped into a 6.3.2 source tree as a few people have asked for
this in 6.3.2 as well.

Attached to the mail is locale-patch.tar.gz. In the archive
there are:
file README.locale
short description
directory src/test/locale
test suite; currently only koi8-r tests, but the suite can be
easily extended
file locale.patch
the very patch; to apply: patch < locale.patch; should be applied
to postgres-6.3.2 (at least I created it with 6.3.2 without any
additional
patches)
Files touched by the patch: src/include/utils/builtins.h
src/backend/utils/adt/char.c src/backend/utils/adt/varchar.c
src/backend/utils/adt/varlena.c

things as well:
* Computes and saves a cancel key for each backend. * fflush
before forking, to eliminate double-buffering problems
between postmaster and backends.
Other cleanups.
