Look at the release notes for 9.6. The descriptions for each item will
tell you what was added/changed or improved e.g.:

https://www.postgresql.org/docs/10/static/release-9-6.html

"
E.13.3.1.11. Reliability

Force backends to exit if the postmaster dies (Rajeev Rastogi,
Robert Haas)

Under normal circumstances the postmaster should always outlive its
child processes. If for some reason the postmaster dies, force backend
sessions to exit with an error. Formerly, existing backends would
continue to run until their clients disconnect, but that is unsafe and
inefficient. It also prevents a new postmaster from being started until
the last old backend has exited. Backends will detect postmaster death
when waiting for client I/O, so the exit will not be instantaneous, but
it should happen no later than the end of the current query.

Changes are back ported to current supported versions that have the same
feature, so if was fixed in 9.6 and existed in 9.5 it was fixed there
also. That would cover fixed bugs up to the last minor release. As to
what is being worked on for the next minor release you will need to wade
through the archives here:

https://www.postgresql.org/list/pgsql-bugs/

Know that there is a regular regular cycle for bug fixes:

https://www.postgresql.org/developer/roadmap/

If there is a show stopper bug a release will happen between the
scheduled dates .
