If one of your PostgreSQL instances is not able to stop, its logs would
tell you what it did not have time to finish. You may perhaps blame the
time it takes for the shutdown checkpoint to finish. You should also
try to use the fast mode of "pg_ctl stop", which makes sure that all
sessions connected are forcibly finished cleanly, allowing Postgres to
not need crash recovery the next time it starts.
