Maybe you should get some actual lawyers to answer this type of
question.  The Chromium license this code cites is 3-clause-BSD
style, which is NOT compatible: the "advertising" clause is
significant.

In any case, writing copyright notices that are pointers to
external web pages is not how it's done around here.  We generally
operate on the assumption that the Postgres source code will
outlive any specific web site.  Dead links to incidental material
might be okay, but legally relevant stuff not so much.
