Yes I also think the same.
But there is no core file in /var/lib/pgsql/dat on my system.
I am trying to find out why this is not generating core while log message

I'm afraid I'm out of ideas on how to get the core dump then.
You could also try attaching gdb to the backend process before it
crashes, and get the backtrace from there. Something along the line

The next obvious question is, is this something we care to backpatch (at
this point, 8.4 is considered backpatch from that perspective), or
should we hold for 8.5?
The only issue now i
The only issue now is a small leak of memory in a function that is only
called a fixed (and very small) number of times per process. Given this,
I'm inclined to say we should put it on hold for 8.5. Thoughts?
Doesn't sound urgent to me. If it were my decision, I'd punt it to 8.5.

The amd64 spintlock instructions use no AMD-specific features. It's
base intel 64bit instruction set. We ship a product with similar such
spin locks and have never had an issue across a large variety of
chipsets (Intel, AMD, and virtualized).
In short, if you can actually run 64bit code,

Random segfaults easily by application bugs ( memory corruption,
