Hi.
1.Didn't you count the overheads when using pgscv with default settings?
2. Which is default frequency update? On graphics it looks like about 15 seconds. Interval cannot be changes?

Hi,

No, didn't. Overhead depends on number of databases/tables/indexes/statements within the instance. If there are too many objects and scrape time become too long, it is worth to review the config and maybe disable collecting metrics from secondary databases.

2. Which is default frequency update? On graphics it looks like about 15 seconds. Interval cannot be changes?

pgSCV polls stats only when configured to send metrics to Weaponry. In basic scenarios it is scraped by Prometheus accordingly to its scrape_config (see scrape_interval).
