无法将服务器上的 postgres 连接到我本地的 postico

Question

when I connect postgres on the server to postico on my local I get this error

could not connect to server: Operation timed out
Is the server running on host "http://159.65.65.203/" (92.242.140.2) and accepting
TCP/IP connections on port 5432?

I could not find anywhere postgresql.conf and pg_hba.conf files, so i created the files, as you see in the below image

I found this explanation but still does not solve my issue

Ubuntu does not use the standard pg_ctl for postgreSQL. Instead, it 
uses pg_ctlcluster.
That in turn controls the different PostgreSQL clusters. When you do 
an install of a new cluster, pg_ctlcluster is smart enough to put
postgresql.conf & pg_hba.conf into separate dirs.
So to be specific, /usr/lib/tmpfiles.d/postgresql.conf is just a tmp 
file that you can ingnore, /etc/postgresql/9.4/main/postgresql.conf is 
the original version for the 9.4 cluster and
/var/lib/postgresql/9.4/main/postgresql.auto.conf is the actual, live
version of the 9.4 cluster that you need to change to affect the 9.4
cluster. Likewise for the pg_hba.conf.

here how i configured postgresql.conf

port=5432
listen_addresses='*'

here how i configured pg_hba.conf

 host    all             all              0.0.0.0/0                       md5
 host    all             all              ::/0                            md5

when i run

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program 
name

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -
tcp        0      0 127.0.0.1:5432          0.0.0.0:*               LISTEN

Clearly 5432 is not open for all connections. when i make an api call using postman seems to work. I use mac currently firewall not on, i have my server on digitalocean use Ubuntu 16.04.6 (LTS) x64.

This is the path of postgres files

postgres@borroupapi:~/9.5/main$

when i run find / -name postgresql.conf i get this

/usr/lib/tmpfiles.d/postgresql.conf

but i cant find the path as logged in postgres user

Answer 1

try this to fix the issue in postgres 9.5 postgresql.conf and pg_hba.conf files are located in

/etc/postgresql/9.5/main/

not in

/var/lib/postgresql/9.5/main/

you have to login as server root user and run each one of the command and that will give where are the files

find / -name postgresql.conf

find / -name pg_hba.conf

in my instance when i ran the command i got this

/var/lib/postgresql/9.5/main/postgresql.conf
/etc/postgresql/9.5/main/postgresql.conf
/usr/lib/tmpfiles.d/postgresql.conf
