I dont think so.
I _think_ that an insert can only ever insert a single row.

I _think_ you ahve to do a separate inssert for each row to be inserted.

But i ma not a postgres experet or an expert on sql and its sematnics,
just auser.
My thoughts above are from my won experience, not any absolute knowledge.
