*I feel it important to add one note to this thread. The version of
PostgreSQL has not been stated, but it is very *

*important to note that the default behavior of pg_ctl has changed between
v9.4 and 9.5.https://www.postgresql.org/docs/9.5/static/release-9-5.html
<https://www.postgresql.org/docs/9.5/static/release-9-5.html>*

-

*Change pg_ctl
<https://www.postgresql.org/docs/9.5/static/app-pg-ctl.html>'s default
shutdown mode from smart to fast (Bruce Momjian)*

*This means the default behavior will be to forcibly cancel existing
database sessions, not simply wait for them to exit.*

*So if the PostgreSQL version is 9.4 or lower, and there are any open
connections, the pg_ctl will wait until all connections terminate (either
normally or *

*are forced off). That "might " explain why pg_ctl never terminated (unless
-m fast was also specified). However, if it is version 9.5 or above, then *

*-m fast is the default so existing connections will not be a problem. *
