Requirements

Database User

This source only uses standard authentication. You will need to create a PostgreSQL user to login to the database with.

Example

sources:
    my-pg-source:
        kind: postgres
        host: 127.0.0.1
        port: 5432
        database: my_db
        user: ${USER_NAME}
        password: ${PASSWORD}

Tip

Use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file.
