[$] Rethinking the PostgreSQL CommitFest model

Many years ago, the PostgreSQL project started holding regular CommitFests to
help tackle the work of reviewing and committing patches in a more
organized fashion. That has served the project well, but some in
the project are concerned that CommitFests are no longer meeting
the needs of PostgreSQL or its contributors. A lengthy discussion on the
pgsql-hackers mailing list turned up a number of complaints, a few
suggestions for improvement, but little consensus or momentum toward
a solution.
