January 2026: In the pgsql-jp/jpug-doc repository, delivered a targeted documentation fix to correct the description of pg_class.relminmxid in the system catalog docs. The translation previously indicated that this column stored all pre-replacement multi-transaction IDs; it is now clarified to reflect that relminmxid is of type xid and holds a single value, and that pre-replacement MXIDs are not stored. The change aligns with the existing translation pattern used for pg_class.relfrozenxid to maintain consistency across system catalog documentation. Impact: clearer documentation, reduced developer confusion, and improved onboarding and support efficiency. Skills demonstrated: careful semantic analysis, translation accuracy, documentation craftsmanship, and commit-level traceability.
