5a1e1d83022 was a minimal bug fix for dc7420c2c92. To avoid future bugs of that kind, deduplicate the choice of a relation's horizon into a new helper, GlobalVisHorizonKindForRel(). As the code in question was only introduced in dc7420c2c92 it seems worth backpatching this change as well, otherwise 14 will look different from all other branches. A different approach to this was suggested by Matthias van de Meent. Author: Andres Freund Discussion: https://postgr.es/m/20210621122919.2qhu3pfugxxp3cji@alap3.anarazel.de Backpatch: 14, like 5a1e1d83022
