/// configuration files, or from environment variables.

/// Example configuration in YAML:
///
/// ```yaml
/// host: localhost
/// port: 5432
/// username: user
/// password: password
/// database: test
/// max_open_cons: 10
/// min_idle_cons: 5
/// conn_max_lifetime:

/// nanos: 0
/// connection_timeout:
/// secs: 15
/// nanos: 0
/// idle_timeout:
/// secs: 3600
/// nanos: 0
