Dear Tom Lane,

Thank you for your message. I understand your point of view. However, the
three documents I cite in my previous message have significant graphical
content, eg. time-memory graphs. At least two of them are relevant, the
third tangentially so. Also, these two files (opt and diag) are 25 and 41
pages respectively in their pdf version. I don't think it would be very
easy to cram these two into an email.

So, in light of that, would it be permissible to attach these documents to
my email, since you want a self-contained email? If so, I hope I do not
fall afoul of spam filters. The two documents are 3.3M (opt.pdf) and 132K
(diag.pdf).

Sincerely, Faheem Mitha.
