TBH, I think this is a horrid idea. We occasionally manually add remarks
like "since version x.y, Postgres does this". Inevitably, that just bulks
up the documentation; and it starts to look seriously silly in a few years
when x.y and all its predecessors are out of support. It'll be a real
mess if we do that for everything.
There might be a use-case for a table of this sort somewhere, but please
not in the main documentation.
