Yeah. The short form of this is that there is not very much difference
between MIT-style and "simplified" (2-clause) BSD-style. Red Hat
(specifically Fedora) decided to lump all such licenses as "MIT-style"
rather than using the phrase "simplified BSD". That's not binding on
anybody else, it's just how they choose to classify licenses.

There is a significant difference between 2-, 3-, and 4-clause BSD
licenses, as the extra clauses ("no-endorsement" and "advertising"
respectively) do make a difference in practice. But Postgres has
never had either of those.
