Should I add checks for a PostgreSQL version from each major version or
just for one from the latest major version and the oldest version supported
? Like just test with 9.5 and 12.x . Same question with Java versions. Is
testing with Java 9 and Java 14 (the latest java release) is enough ? Or
each of java versions in between Java 9 and 14 should be tested as well.
