wget https://github.com/zubkov-andrei/pg_profile/releases/download/4.11/pg_profile--4.11.tar.gz
tar -xzf pg_profile--4.11.tar.gz -C $(pg_config --sharedir)/extension

Deploy Postgresql on Oracle Linux 8
#

Why Select 16 Version?
#

因為在 AWS 的長期支援板(LTS) 當前是使用 16.8，所以可以預期的是在未來的擴充套件有級大的可能是在 16.8 上進行開發。如果要採用社群維護可以參考Versioning Policy
