• [FEATURE] Add --max-open-conns and --max-idle-conns options, allowing the exporter to execute metric queries concurrently if set to a number greater than 1
• [FEATURE] Add pg_exporter_metric_query_last_duration_seconds and pg_exporter_metric_query_errors_total metrics, which describes the last execution duration of metric queries and the number of query errors that have happened so far, respectively. The metrics cover custom user queries (specified with --extend.query-path) as well as the default metrics (--no-disable-default-metrics and --no-disable-settings-metrics).
