There are (I and several of my colleagues, for example) - but they're paid by employers having us work on postgres, rather than a foundation or such.

There unfortunately - personal opinion, not as a core team member - is no good way to fund a "partial" developer for postgres right now.

On a smaller scale than employing a dedicated postgres developer, regularly testing the in-development release (and reporting bugs!), doing ad-hoc testing, patch review etc are a bit easier to start with.
