PGW: A PGBACKREST INTERLUDE:

(Andreas Scherbaum, Jimmy Angelakos)

Andreas Scherbaum and Jimmy Angelakos presented a quantitative analysis of the PostgreSQL CommitFest process using data collected from the CommitFest application itself.

The talk showed how PostgreSQL development has scaled significantly over the years. In 2015, CommitFest handled 418 patches from 125 authors, while in 2025 it handled 885 patches from 272 authors — roughly doubling both patch volume and contributor count. However, reviewer and committer capacity has not scaled equally well. The speakers showed that 72.1% of “Needs Review” patches currently have no reviewer assigned, and 196 out of 331 active patches in the current CommitFest have zero reviewers.
