    Have a look at the PostgreSQL engine integration here where you can perform SELECT and INSERT queries on ClickHouse on data stored in remote PostgreSQL.

    You can also make use of table function as well.

    You ingest data from Postgres into Clickhouse using:

    • External ETL tools like Airbyte and make a connector from Postgres to Clikhouse

    • Clickhouse integrations table engine to make a view from Clickhouse to Postgres data, after that use insert into query to insert data from that view into the real Clickhouse table
