Recommendation of PostgreSQL: All the new versions work perfectly fine. We cannot exclude that future versions might have problems. In general, i would recommend for production the newest major version of PostgreSQL, with a release version greater than 0.
All the versions in the "Require" section of the release notes are minimal requirements (meaning this version or newer),
Added tooltips for storing the rationales. Had to add them in title attributes of wrapping anchor tags because CKEditor strips td titles (i.e., the "links" are only there to preserve these tooltips.)
If anyone sees inaccuracies or wants to refine any of the assumptions, please let me know — happy to adjust.
