That's darn odd. But please be more specific: what's "open the database"? Start the postmaster? Start a psql? Issue a query? > Does the shared memory stuff use disk at all? 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. regards, tom lane
