I think it was just that Bruce hasn't gotten to it.

I just checked out a new cvs copy and applied the patch, and did something
like the following:
create table a1(a int unique, b int, c int, unique(b,c));
insert into a1 values (1,1,1);
create table a2(a int references a1(a), b int, c int, foreign
key(b,c) references a1(b,c) initially deferred );
begin;
insert into a2 values (1,1,1);
insert into a2 select * from a2;
[repeated a bunch of times until it'd be inserting 64k rows]
and got an error on writing the disk event handle and a signal 11:
ERROR: Can not open first disk event file handle for
/usr/local/pgsql/data/base/17139/pgsql_tmp/pgsql_tmpdeftrig_555-000000001
The connection to the server was lost. Attempting reset: LOG: server

The backtrace from the core looked like:

looks like it was passing a NULL file handle if it couldn't be opened.
