I updated my Xubunutu, It was originally 19.04 when I install on this labtop, I think I did one update in the past, now on Xubuntu 19.10.
Postgres was working just prior to the upgrade, I think I may have two versions of postgres running but many of the solutions I've seen don't seem to work.

The fix came in by uninstall all the packages from the dpkg results in the OP, then reinstalling with sudo apt-get install postgresql.

I'm trying to upgrade PostgreSQL from 11 to 13 on a Debian system, but it fails. I have a single cluster that needs to be upgraded:
$ sudo -u postgres pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5432 online postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
Here's what I've tried to upgrade it:
$ sudo -u postgres pg_upgradecluster 11 main
Stopping old cluster...
Warning: stopping the cluster using pg_ctlcluster will mark the systemd unit as failed. Consider using systemctl:
sudo systemctl stop postgresql#11-main
Restarting old cluster with restricted connections...
Notice: extra pg_ctl/postgres options given, bypassing systemctl for start operation
Error: cluster configuration already exists
Error: Could not create target cluster
After this, the system is left in an unusable state:
$ sudo systemctl status postgresql#11-main.service

Luckily, rebooting the system brought the old cluster back online, but nothing has been upgraded. Why does the upgrade fail? What are "the steps required by its unit configuration"? How can I upgrade PostgreSQL with minimal downtime?
I found the source of my problem: a configuration file owned by the wrong user (root instead of postgres) that could not be removed by the pg_dropcluster command because I ran it as the user postgres.
For future reference, here are the correct steps to upgrade a PostgreSQL cluster from 11 to 13:
Verify the current cluster is the still the old version:
$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5432 online postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
13 main 5434 down postgres /var/lib/postgresql/13/main /var/log/postgresql/postgresql-13-main.log
Run pg_dropcluster 13 main as user postgres:
$ sudo -u postgres pg_dropcluster 13 main
Warning: systemd was not informed about the removed cluster yet.
Operations like "service postgresql start" might fail. To fix, run:
sudo systemctl daemon-reload
Run the pg_upgradecluster command as user postgres:
$ sudo -u postgres pg_upgradecluster 11 main
Verify that everything works, and that the only online cluster is now 13:
$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5434 down postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
13 main 5432 online postgres /var/lib/postgresql/13/main /var/log/postgresql/postgresql-13-main.log
Drop the old cluster:
$ sudo -u postgres pg_dropcluster 11 main
Uninstall the previous version of PostgreSQL:
$ sudo apt remove 'postgresql*11'
The Debian packages create a cluster automatically when you install the server package, so get rid of that:
pg_dropcluster 13 main
Then stop the v11 server and try again.
when I try to boot Ubuntu, it never finishes the boot process because it appears the message "Failed to start PostgreSQL Cluster 10-main." I also get the same message with 9.5-main. But lets focus on 10.
When I execute:
systemctl status postgresql#10-main.service
I get the following message:

PC_info is information about my computer (user, date..) not relevant
I got this error from one day to an other without touching anything related to Database Servers.
I tried to fix it by my self but nothing worked
Writing the command
service postgresql#10-main start
I get
Job for postgresql#10-main.service failed because the service did not take the steps required by its unit configuration
See "systemctl status postgresql#10-main.service" and "journalctl -xe" for details.
Running this two command I get the message from the beginning.
Anyone has an idea of what is happening? How I can fix it?
I had same issue, I followed below steps,
Error status :
pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
10 main 5432 down postgres /var/lib/postgresql/10/main
/var/log/postgresql/postgresql-10-main.log
Applied Solution :
sudo chmod 700 -R /var/lib/postgresql/10/main
sudo -i -u postgres
postgres#abc:~$ /usr/lib/postgresql/10/bin/pg_ctl restart -D /var/lib/postgresql/10/main
After Solution status :
pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
10 main 5432 online postgres /var/lib/postgresql/10/main
/var/log/postgresql/postgresql-10-main.log
as mentioned by #gruentee in comment above,
/usr/lib/postgresql/10/bin/pg_ctl restart -D /var/lib/postgresql/10/main -l /var/log/postgresql/postgresql-10-main.log -s -o '-c config_file="/etc/postgresql/10/main/postgresql.conf"'
started the postgresSql DB. Dont forget to
sudo -i -u postgres
before issuing above command
I was facing the same challenge, I try a lot of methods but none work for me till I try these commands below
sudo apt-get -y install postgresql
sudo systemctl start postgresql#15-main.service
pg_lsclusters
then everything started working fine, but please the version of postgresql i'm using is 15 that's you are seeing 15 in the second command so in your case you substitute it with the version you are using
I have installed postgresql and done all the setup and created db and tables yesterday but today morning I got sudden this error
I have also uninstalled and installed postgresql but still same error. And also I have observed that when installed freshly it is working fine but once I shutdown or restart my system I'm getting the below error.
psql:
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I have tried all the solutions given in all the mediums but I'm not able to resolve the issue so I'm posting this question again with my outputs.

I even tried to restart the postgres still same issue.
**sudo /etc/init.d/postgresql status**
I had exactly this error message, and this is how I resolved it.
In the log file at /var/log/postgresql/postgresql-13-main.log, these lines were present:
2021-09-15 08:26:04.936 UTC [46258] LOG: invalid value for parameter "lc_messages": "en_US.UTF-8"

Examine the log output.
This is caused by missing locales, with these possible fixes:
localedef allegedly fixes this according but I had no luck with this.
localedef -i en_US -f UTF-8 en_US.UTF-8
change postgresql.conf and use a locale that does exist (en_GB in my case)
lc_messages = 'en_GB.UTF-8' # locale for system error message strings
lc_monetary = 'en_GB.UTF-8' # locale for monetary formatting
lc_numeric = 'en_GB.UTF-8' # locale for number formatting
lc_time = 'en_GB.UTF-8' # locale for time formatting
post settings
port = 5432 # (change requires restart)
Port was wrong on my PostgreSQL 13 default config (was 5433) and required a change back to the default 5432. I presume this was a result of upgrading from v11 so it gave it a new port number.
After these changes, PostgreSQL needs to restart and it should now function correctly without errors in the log, and the psql command working as expected.
Try this:
sudo -u postgres -i
And then:
initdb --locale $LANG -E UTF8 -D '/var/lib/postgres/data/'
exit
This has worked for me so far
I was running a Django application with Postgres as backend database. It was working fine. All of a sudden, today I saw my database connection is refusing in the production server. So I logged into my server and tried to:
psql
and then it was showing this error:
psql: could not connect to server: No such file or directory
Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
The file listed above does not seem to exist.
I checked if my Postgres is running or not with:
/etc/init.d/postgresql status
and it was returning with SUCCESS message.

Still, I stopped and started postgres again.
I checked if there any other postgres task running or not with:
ps -ef | grep postgres
And it returned:
root 5210 5117 0 10:21 pts/0 00:00:00 grep --color=auto postgres
So there is no other Postgres.
I even checked if my Postgres accidentally got deleted or not with
dpkg -l | grep postgres
and it returned

ii postgresql-contrib-9.5 9.5.10-0ubuntu0.16.04 amd64 additional facilities for PostgreSQL
So there is no rc instead of ii, which means it has not been uninstalled.
I have tried every other solution in the internet but uninstalling Postgres. Didn't work for me. I might be doing something very silly. I don't want to uninstall and lose my data.
Run the following command to check which port your PostgreSQL server is actually running on:
[root#server ~]# netstat -a | grep .s.PGSQL
unix 2 [ ACC ] STREAM LISTENING 2534417 /var/run/postgresql/.s.PGSQL.5432
I can see from this output that my server is listening on port 5432 and also that the file is created in /var/run/postgresql/.s.PGSQL.5432
You can then update /etc/init.d/postgresql to include the lines
PGPORT=5432
export PGPORT
and update your postgresql.conf file which is located in your data directory and set the port key/value to port=5432
and then restart your PostgreSQL server
[root#server] service postgresql restart
I had installed postgresql and postgis on new Debian stable (Stretch 9) like I did it on Debian 8.
When I'm connecting as postgresql user, I had an error:
postgres#servername:~$ psql
psql: n'a pas pu se connecter au serveur : Aucun fichier ou dossier de ce type
Le serveur est-il actif localement et accepte-t-il les connexions sur la
socket Unix « /var/run/postgresql/.s.PGSQL.5432 » ?
Translation:
psql: cannot connect to server: No file or directory of this kind. Is the server locally activated and does it accept connection on Unix Socket « /var/run/postgresql/.s.PGSQL.5432 » ?
So, I would like to have a look on my config file, but /etc/postgresql directory is empty ! There is no pg_hba.conf and no postgresql.conf !
root#servername:/etc# locate pg_hba.conf
/usr/share/postgresql/9.6/pg_hba.conf.sample
What did I wrong when installing postgresql?
Here is the command that I have launch to install it:
# apt-get install apache2 php phppgadmin postgresql postgresql-client postgis
The service seems to be running:
root#servername:/etc# service postgresql status

# ls /etc/postgresql/9.6/main
