[Catalyst] Cat + DBIC + DBD-Pg + mpm_worker

Hi,
I know the Cat cookbook suggests one should use mod_perl only with the
preforking MPM.. but I wanted to try with the worker (ie. threaded) MPM anyway.
DBD-Pg had some thread-safety work done years ago, and I meant to be fine..
However I'm seeing errors like this one:
Couldn't render template "undef error - DBD::Pg::db STORE failed:
handle 2 is owned by thread 84e5bf0 not current thread 8fe48f8 (handles can't
be shared between threads and your driver may need a CLONE method added) at
/usr/lib/perl5/vendor_perl/5.8.8/DBIx/Class/Storage/DBI.pm line 723.
I've checked, and I am running a recent version of DBD-Pg, that does indeed
have the required CLONE function. (Ver 2.8.6)
Are there any known issues with Cat+DBIC+DBD-Pg here? Or maybe I just have
screwed something else up..
thanks,
Toby
PS. I've used DBI, Pg and mpm_worker with modperl some years ago successfully,
I'm sure.. but in more recent years I've used lighttpd+fastcgi app servers
instead. However I figure it's worth checking back to see how things are going
with threaded apache again..
