How to use postgresql as backend?

I have tried postgresql as backend for storing metrics with Prometheus remote write providers. But there is no data shown in my database. Here is my question:

Prometheus remote write API with storage providers. Here storage providers list all available database including PostgreSQL/TimescaleDB. I go into this link but find that this provider is supported for TimescaleDB, not native postgresql.

But in this link Export metrics to external time-series databases | Learn Netdata, it shows that postgresql is supported.

Which storage provider should I use if I wanna export netdata metrics to native postgresql?

@oleotiger asked the same question on GitHub, so I am posting here the discussion for posterity.
