error: connection to server on socket...
Using the following command on my Debian 12 machine:
/*sudo apt-get install postgresql postgresql-15 postgresql-client-common
postgresql-common postgresql-contrib postgresql-doc phppgadmin
*/
and following the instruction on this
<https://wiki.debian.org/PostgreSql#User_access> web page I have
installed PostgreSQL-15.
The installation went smooth, until the following command was issued :
/*sudo -u postgres psql*/
... I get an error message that reads:
/*could not change directory to "/home/my_account": Permission denied*//*
*//*psql: error: connection to server on socket
"/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory*//*
*//* Is the server running locally and accepting connections on that
socket?*/
What can I do to resolve this issue?
Thanks in advance.
_*Addendum*_
I tried this, but to no avail : /*sudo systemctl start postgresql*/

When executing the `sudo` command above:
* as which user are you doing that (you can see that via `id`)?
* in which directory are you executing it (you can see that via `pwd`)?
* what is the home directory of the postgres user (you can see that via
`grep postgres /etc/passwd`)
* what does `ls -ld /var/run/postgresql/; ls -l
/var/run/postgresql/.s.PGSQL.5432` show?

This here is on SuSE Linux:

We normaly use the TCP/IP port 5432 to connect to the server.

Yeah. Look to see if there's a socket file there, and if so try
sudo -u postgres psql -h /tmp
In the longer term, this indicates that you have a psql that did
not come from the same packager as your server, because the server
thinks the default socket location is /tmp, but psql (or really
the libpq.so it's using) thinks the default location is
/var/run/postgresql. That's a build-time choice that some
packagers make because $standards. So the long-term fix is to
not have a hodge-podge of different Postgres installations on
the same machine.
BTW, you can ignore the "could not change directory" warning.
That's expected when starting "sudo -u postgres psql" in a
directory that the postgres user can't read.

Ah! Adrean, here is something interesting.
/*pg_lsclusters*/ displays the following information

What is version 12 is doing there, I thought that I had completely
removed it and replaced it with version 15!!
Should I remove that log file?

You didn't, read:

and
/messages/by-id/33f0fc61-2d0f-60bd-e0ed-4cada3c30301@aklaver.com
The clue is "binaries_missing".
You remove(ed) all the files except the conf files.
Should I remove that log file?
Run:
sudo apt purge postgresql-12
That will take care of removing all the conf files.
To connect you need to specify the correct port, 5433 or do:
sudo vi /etc/postgresql/15/main/postgresql.conf
and change
port = 5433
to
port = 5432
Then restart the server.
