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.

Through some minor changes, I have been able to compile the libpq
client libraries on the Win32 platform. Since the libpq communications
part has been rewritten, this has become much easier. Enclosed is
a patch that will allow at least Microsoft Visual C++ to compile
libpq into both a static and a dynamic library. I will take a look
at porting the psql frontend as well, but I figured it was a good
idea to send in these patches first - so no major changes are done
to the files before it gets applied (if it does).

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!
