There is an interesting thread over at postgres, started of by Bruce
Momjian:

If you're interested, read the whole thread.

The picture I get is that the overall amount of developer resource
isn't very different from ours, regardless of what they say in
interviews.

Also, they come across as a bit disorganised. We may have our debates
over FB3 merge process, but overall we're focussed and have managed
to tie company involvement into the core project.

Our structure, with a Foundation, an admin committee and Dmitry
Yemanov as the trusted "keeper of the core" seems to work relatively
well.

We can be proud of ourselves!
