[$] Lessons on attracting new contributors from 30 years of PostgreSQL

The PostgreSQL project has been
chugging along for decades; in that time, it has become a thriving open-source
project, and its participants have learned a thing or two about what works in
attracting new contributors. At FOSDEM 2026, PostgreSQL contributor Claire
Giordano shared some of the lessons learned and where the project is still
struggling. The lessons might be of interest to others who are thinking about
how their own projects can evolve.
