Re: [HACKERS] postmaster dies (6.5.3)

Thanks for the patch.  I think I'm going to upgrade to FreeBSD-3.3 and
PG-6.5.3 tonight.  Will I still need the patch with 6.5.3?  I'm also going
to do a connection test on another offline server to see if it is indeed a
load problem.  I'll post the results if anyone is interested.

Thank you for the help,
Matthew
