[Does some further testing] The limit is high, but nonetheless Postgres is
running out of handles. Setting <max_connections> to 10000 and starting
postgres _without_ any connection consumes 40000 handles. This correspodends
to the 4 Postgres processes running after the server was started. Every new
connection consumes another 10000 handles.
I don't know the Postgres code involved, but it seems that every backend
consumes at least <max_connections> handles. Hence increasing this value will
have the opposite effect once a certain threshold is met.
