But we don’t call out “new features” in the documentation. Just
“features”. And so when the pg_upgrade docs says “pg_upgrade supports
upgrades from 9.2.X and later” then unless there is a note to the contrary
(which there is not here) that applies to everything pg_upgrade does.
Put differently, read the docs as if you were unaware in which version that
capability was introduced. This is the style/assumption the documentation
is written in/using.
