As in previous years, I've pulled together a few statistics on code contributions to PostgreSQL. See previous posts in this series for methodology and caveats. I calculate that, in 2023, there were 221 people who were the principal author of at least one PostgreSQL commit. 66% of the new lines of code were contributed by one of 18 people, and 90% of the new lines of code were contributed by one of 50 people. Here they are. Asterisks indicate non-committers.
