I did this interview with brianc[1] of node-postgres a few weeks ago. This situation of a widely used project putting a lot of pressure on a small group or sometimes just one person is quite common in open source software.
Brian is a very generous guy, so please consider supporting him if you get value out of his work on his patreon[2].
