- `prefer`: This mode will try to establish a secure TLS connection if possible, but will connect insecurely if the server does not support TLS.
- `disable`: This mode will not attempt to use a TLS connection, even if the server supports it.
- `pg_sslrootcert`: Optional parameter specifying the path to a custom PEM certificate that the connector will trust.
- `pg_connection_pool_min`: Optional. The minimum number of connections to keep open in the pool, lazily created when requested. Default is `5`.
- `connection_pool_size`: Optional. The maximum number of connections to keep open in the connection pool. Default is 10.
- `pg_connection_pool_min_idle`: Optional. The minimum number of idle connections to keep open in the pool. Default is `1`.
- `connection_pool_size`: Optional. The maximum number of connections to keep open in the connection pool. Default is `5`.

Configuration `params` are provided in the `acceleration` section of a dataset.
