Bug reference: 16531
Logged by: R F
Email address: bee.lists@gmail.com
PostgreSQL version: 10.6
Operating system: CentOS 7
Description:
I only had this in postgresql.conf:
listen_adresses = '192.168.1.50'
The machine was properly functioning on 'localhost' in an application I had
on the same machine.
In pg_hba.conf:
local all all trust
host all all 127.0.0.1/32 trust
With these directives, the machine, from what I understand, shouldn't be
able to reach into localhost.
