Reviewed-by statistics for PostgreSQL commits in 2025 ====================================================== Methodology ----------- Parsed Reviewed-by: tags from git log for commits dated 2025-01-01 through 2025-12-31 on the following branches: origin/master origin/REL_13_STABLE (EOL November 2025) origin/REL_14_STABLE origin/REL_15_STABLE origin/REL_16_STABLE origin/REL_17_STABLE REL_18_STABLE was excluded: it is an active development branch and its 2025 commits overlap substantially with master. For stable branches, a Reviewed-by entry is counted only if the same (reviewer email, commit subject) pair does not already appear in master commits for 2025. This avoids double-counting reviews of patches that were committed to master and then backpatched. Known aliases (same person, multiple email addresses) were merged manually: Alvaro Herrera, Chao Li, Fujii Masao, Aleksander Alekseev, Alena Rybakina, Andrei Lepikhov, Andy Fan, Daniel Gustafsson, David Rowley, David Steele, Guillaume Lelarge, Heikki Linnakangas, Jacob Champion, Matheus Alcantara, Peter Eisentraut, Robert Haas, Sami Imseih, Stepan Neretin, Thomas Munro, Tomas Vondra. Name spelling follows what appears most frequently in commit messages.

Patches reviewed on the mailing list but committed without a Reviewed-by tag are not reflected here. Conversely, a single large patchset committed as multiple commits may result in the reviewer being counted multiple times. - Only 52.9% of master commits carry a Reviewed-by tag. The actual number of people doing review work is larger than this table shows. - The long tail (ranks 89-112, all with 3 or fewer entries) is noisy: small counts are sensitive to whether a committer included the tag. - Corrections welcome, especially for name aliases not yet merged.
