If you give each key a unique name, e.g. "invoices.invoice_id" instead of "invoices.id", then you can use the "natural join" and "using" operators with no worries. E.g.

SELECT * FROM invoices JOIN invoice_lines USING (invoice_id)

instead of

SELECT * from invoices JOIN invoice_lines
    ON invoices.id = invoice_lines.invoice_id

SQL is verbose enough without making it more verbose.
