    [server] implement dynamic database pooler · e94f2349ee21

    Opening too much database connection has a cost at startup and also PostgreSQL
    as a maximum number of connection (100 by default).
    This get worse when starting multiple wsgi processes, since each process has
    its own database pool.
    Instead of opening `connections-pool-size` connections to the database at
    startup, just open one and open more only when needed.
