That's darn odd.  But please be more specific: what's "open the
database"?  Start the postmaster?  Start a psql?  Issue a query?

No, I can't see that there would be any connection there.

Perhaps the next thing to do is to strace (ktrace, trace, truss,
whatever system-call tracing utility you got) the postmaster and
child processes.  If we could determine what system call is hanging up,
we might be a little closer to solving the mystery.
