سؤال
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 0.0.0.0:80 0.0.0.0:* LISTEN -
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
29761/postgres
tcp6 0 0 :::22 :::* 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
المحلول
fixed 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
