FWIW that's a list of "open items" for PostgreSQL 10 release. So it's not really a "global" authoritative list of open issues, but something the project uses to make sure we deal with all known issues in the development version before the first release. The claim that PostgreSQL does not have a bug tracker is not entirely accurate - there is no bugzilla/debbugs/...-style bugtracker (although it's a recurrent topic in discussions), but we do have pgsql-bugs mailing list. Which is mostly fine, as long as you fix bugs promptly and don't keep unsolved bugs lying around for years. If you need to know what was fixed in a particular release, see either the release notes (high-level summary), or commits in the stable branches (those are typically just bugfixes, and the commit messages usually include a link to the relevant pgsql-bugs thread).
