Bug reference: 14115
Logged by: Andreas Schmidt
Email address: andreas.schmidt1982@googlemail.com
PostgreSQL version: 9.5.2
Operating system: Windows Server 2008 R2 Standard
Description:
In our postgresql.conf we defined the following addresses:
listen_addresses = 'localhost,192.168.1.2'
PostgreSQL stopped listening to 192.168.1.2 while we still could connect
using localhost.
After we restart the PostgreSQL server, we can connect to 192.168.1.2
again.
The system was not changed during the time period when the problem happened.
