Well they are not. They are available under the PostgreSQL license overall
and *may* have originated under a different (but still very much compatible
with ALv2 -- so no alarm bells ;-)) license.

Why? It would be perfectly fine for PG project to include, lets say an MIT
source code. MIT is a compatible license. Whether the fact that the code
was originally licensed under MIT is reflected in the header of that
*particular*
file is an open question. That's why I don't feel comfortable putting
the overall
PG  licensed header there on my own. It may not be, strictly speaking illegal,
but it makes me uncomfortable. And since the NOT putting it there has no
downside (aside from making scanning a bit more complex) I'd prefer for the
file to remain unmodified.

I think we're talking slightly past each other -- I told you I do KNOW that they
are licensed under the different ALv2 compatible license.

that they are not.

Again, no reason to speculate -- we do KNOW what the overall license on
these files are -- that is PostgreSQL license. We may not know what the original
license on each individual file was, but we do know that it was compatible
with the PostgreSQL license.

Sounds good!

Thanks,
