Rough estimate of number of downloads per year/month/day?

I know this is the 1 million dollar question and we miss most of the data.

But I'd love to have some numbers about the downloads from the community
website. Something like: number of downloads in 2012 so far, or a daily
average in 2012 or something like that. If you have a series of data per
day, that'd be cool.

The reason is that today an open source conference is takin place in
Italy and it was reported that MySQL has 70000 downloads per day. I have
asked more information about the source and the specific product, but
I'd love to have a number about PostgreSQL (even if partial).

Thanks.

Cheers,
Gabriele
