[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.

You can as well type complex queries using the RQL_ query language,
used every where to build dynamic pages of this site.

You can use one of the following prefixes to specify which kind of search you
want:

* `rql` : RQL query
* `text` : full text search
