not able to connect to postgres db
I am not able to connect to postgresql database of pega 8 vm of the system architect essentials course. I am using host only adapter on virtualbox and so trying to connect from the host machine. I read the other thread on this forum about this issue and first found DB connection information from the installed tomcat's prweb.xml
driverClassName="org.postgresql.Driver" url="jdbc:postgresql://localhost:5432/pega" username="pega" password="pega"/>
Then I modified the postgresql.conf and pg_hba.conf and placed them back in the path which was /var/lib/pgsql/9.4/data
the change to pg_hba.conf was to add the line
host all all Proprietary information hidden/0 trust
the change to postgresql.conf was to uncomment
listen_addresses=*
I restarted VM
Not sure if the path is correct, but this is the only place where I found pgAdmin4 files that had current date as the last modified timestamp.
I am still getting the same error which is

I am still getting the same error which is
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" ( Proprietary information hidden) and accepting TCP/IP connections on port 5432?
I used Proprietary information hidden instead of localhost and got same error as above. Please guide how to proceed.

I think the host address will vary, did you try using the host address which you are using for Pega login.

Thank you for the suggestion. I just tried using the host address Proprietary information hidden now and unfortunately received the same error. I am attaching the two files - pg_hba.conf and postgresql.conf that I am using. May be there is some mistake in them. Please review if possible.

I tried with the below configuration and it worked. Used password as "postgres". Could you please try the same once.

I tried with postgres as username/password following the example in the screenshot. However I still received the same error. So, the conf files could be wrong. Could you kindly share the pg_hba.conf and postgresql.conf files that you have used.
I also downloaded senior system architect course vm and tried to connect to that database. But received same error. The pgsql 9.4 folder is present in same location as the SA essentials course vm. So maybe I updated the configuration files incorrectly. Please help.
