Sorry about the long delay; I retested with the 8.3-beta2 installer,
still Win2003 SP2 32bit.
I stopped the test at 824 connections because I was about to run out
of memory (1.25GB RAM + 3.75GB swap), but postmaster VM space usage
was only 191MB.
As for desktop heap, only 65KB of the service heap was allocated, or
about 80 bytes per connection. No danger of hitting limits in the
kernel memory pools either.
Available RAM seems like a pretty reasonable limit to me ;)
