I also met this error yesterday. Default PostgreSQL limit for incoming connections is 32 (actually 30 for ordinary users, because 2 are reserved for superusers). You can change this from postgresql.conf.
In our case the problem was pgAdmin, which creates a new connection for every database you click on. You can use `ps ax | grep postgres` in Linux to see active connections.
