I tend to agree with Bruce on this: max_connections means
max_connections. Therefore, the number of backend slots is
max_connections, of which max_connections - max_admin_connections
are available to non-superusers.
(There is provision in the existing code for one extra child process
for checkpoints, but it's not a "real" backend and so it's reasonable
not to count it against max_connections.)
