[ADMIN] PostgreSQL 9.4.13 is facing issue in shutting down

Hi,

Recently we have updated our PostgreSQL version from 9.4.12 to 9.4.13. With version 9.4.13 while trying to stop the PostgreSQL server, database is facing issues in shutting down. The problem probably occurs because of the WAL sender process not getting terminated on shutdown request. 

ps output:
postgre+  7915  0.0  1.9 589772 39528 ?        S<   09:11   0:00 /..../bin/postgres -D /.../postgresql -h 0.0.0.0 -p 5432
postgre+  8617  0.0  0.4 590760  8344 ?        S<s  09:13   0:00 postgres: wal sender process replicator xx.xx.xx.xxx(45948) streaming 0/4000090    


Sequence of events in log:
FATAL:  terminating connection due to administrator command
LOG:  received fast shutdown request
LOG:  aborting any active transactions
LOG:  autovacuum launcher shutting down
LOG:  shutting down
LOG:  database system is shut down

We are using pg_ctl fast mode to shutdown the postgres server.

This is probably the same issue as reported here:
https://www.postgresql.org/message-id/1434ad79-ab0d-d6a9-4ea2-1afb1c06adaf%402ndquadrant.it

You can try the patch attached there, or downgrade to 9.4.12 while this
issue is being investigated.
