Thomas,
Thanks for your offer to run some tests on different OSes and filesystems
that you have. Anything you can provide here would be much appreciated. I
don't have anything other than our native SmartOS/ZFS based configurations,
but I might be able to setup some VMs and get results that way.

Peter,
Thanks for your feedback. I'm happy to change the name of the tunable or to
update the man page in any way. I have already posted an updated patch
with changes to the man page which I think may address your concerns there,
but please let me know if that still needs more work. It looks

Hi Robert,
I'm new to the Postgresql community, so I'm not familiar with how patches
are accepted here. Thanks for your detailed explanation. I do want to keep
pushing on this. I'll respond separately to Peter and to Tomas regarding
their emails.
Thanks again,
Jerry

It's not, but I'm working on a patch
The following review has been posted through the commitfest application:
make installcheck-world: tested, passed
Implements feature: tested, passed

This patch applied cleanly and worked as expected.

I think we actually have some decent ideas how to make that less

direct malloc())

Collegues,
I've discovered that in the branch REL_11_STABLE there is shell script
src/bin/pg_upgrade/test.sh which doesn't work under Solaris 10.
(it uses $(command) syntax with is not compatible with original
Solaris /bin/sh)

Hello PostgreSQL Community!
Not long ago I faced the situation concerning ODBC/libpq client hanging in
case of some network problems.
I had a discussion regarding this issue within pgsql-o...@postgresql.org
and got some suggestions.
Here is this discussion:
