I can share a connection across threads in the worker mpm with no problem, I've had ab thrash the hell out of it without any problems.

My problem isn't managing a pool of connections... it's if process A creates the connection, process B can use it with no problem, but if process C tries to use it, it barfs and spikes in a function in libpq, i think it was pgbytes.
You can't really share connections across processes. Across threads, perhaps. But, sharing them across processes is asking for trouble. You'd usually be relying upon shmem which is tricky and not really meant for sharing shm-able data structures. (Some custom OS techniques might be available, but they wouldn't be portable.) -- justin
