I think you're running into a processes-per-user limit, preventing the
postmaster from spawning more backend processes. You can and should
raise that limit (see your kernel documentation for details --- without
knowing what platform you're running on, I can't help). But you should
also rethink the strategy of opening a separate database connection for
each individual query. The overhead of doing things that way is
enormous.
