This does vary across countries, and fields. In UK I was a bit surprised that you're not expected to publish at all before post-doc. In Finland usually at least 3 peer reviewed (first author) papers are required for a PhD in my field (cognitive science). In some fields (e.g. many engineering fields) even more. And PhD grants are typically for three to four years. It is ridiculous and the paper quality is what you'd expect.
