I've created the PR #203 .

Although you may already know, you can use INET type with the current embulk-output-postgresql by setting column_options.

out:
    type: postgresql
    ...
    column_options:
    inet_column: {value_type: string}

Thanks! I only tried with "type". It worked with the proposed workaround.

That's great!
