Reviewed-by statistics for PostgreSQL commits in Q1 2026 ========================================================= (2026-01-01 through 2026-03-31) Methodology ----------- Parsed Reviewed-by: tags from git log for commits dated 2026-01-01 through 2026-03-31 on the following branches: origin/master origin/REL_14_STABLE origin/REL_15_STABLE origin/REL_16_STABLE origin/REL_17_STABLE origin/REL_18_STABLE REL_13_STABLE is excluded: it reached end-of-life in November 2025 and has no commits in Q1 2026. REL_18_STABLE is included as a proper stable branch: it branched from master on 2025-06-29 (PG18 feature freeze) and receives only bug fixes in Q1 2026. 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 the quarter. This avoids double-counting reviews of patches that were committed to master and then backpatched. Known aliases (same person, multiple email addresses) were merged: Alvaro Herrera, Chao Li, Fujii Masao, Heikki Linnakangas, Zsolt Parragi, Viktor Holmberg, Surya Poondla, Aleksander Alekseev, Andrei Lepikhov, Daniel Gustafsson, Jacob Champion, Matheus Alcantara, Peter Eisentraut, Robert Haas, Sami Imseih, Thomas Munro, Tomas Vondra. Name spelling follows what appears most frequently in commit messages. A few entries in the lower ranks appear to be GitHub handles rather than real names (torikoshia, songjinzhou, zengman, Jinbinge); these are reproduced verbatim from the commit log. One entry (Ilya Cherdakov) was transliterated from Cyrillic as it appeared in the commit message.

Most backport commits carry the same Reviewed-by lines as the original master commit and are therefore not counted again. - Corrections welcome, especially for name aliases not yet merged.
