[server] Make connection pooler configurable and set better default values Drop the configuration connections-pool-size and add new configurations options: * connections-pool-min-size. Set to 0 by default so we open connections only when needed. This avoid opening min-size*processes connections at startup, which is, it think, a good default. * connections-pool-max-size. Set to 0 (unlimited) by default, so we move the bottleneck to postgresql. * connections-idle-timeout. Set to 10 minutes. I don't have arguments about this except that this is the default in pgbouncer.

Startup views
-------------

Startup views are views requiring no context, from which you usually start
browsing (for instance the index page). The usual selectors are
:class:`~cubicweb.predicates.none_rset` or :class:`~logilab.common.registry.yes`.

You'll find here a description of startup views provided by the framework.

.. automodule:: cubicweb.web.views.startup


Other startup views:

*schema*
    A view dedicated to the display of the schema of the instance
