It's not actually that unreasonable for a doc patch ;)

Agreed. But it does explain why it's not shown *as an attachment*.

The archive code appears to actually try to handle the case of multiple inline
plain text attachements, from what I can see:
https://git.postgresql.org/gitweb/?p=pgarchives.git;a=blob;f=loader/lib/parser.py;hb=HEAD#l381
 381             # If we have already found one text/plain part, make all
 382             # further text/plain parts attachments
 383             if self.attachments_found_first_plaintext:


So there's something more than just the content-disposition: inline; going on
I think?

Huh. I think you're right. I guess I was just reading it too quickly.
 
And yup, there's the bug.

Line 388 gets the payload in this case -- which returns in type "bytes".
Line 395 verifies that it's a string (which it isn't).

This is a bug in the conversion to python 3.

I've applied a fix and re-parsed the message.

Thanks for being persistent!
