Re: error: connection to server on socket... - Mailing list pgsql-general

Ah! Adrean, here is something interesting.

pg_lsclusters displays the following information

Ver Cluster Port Status                Owner    Data directory              Log file
12  main    5432 down,binaries_missing postgres /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log
15  main    5433 online                postgres /var/lib/postgresql/15/main /var/log/postgresql/postgresql-15-main.log

Due to matters of security let us assume that the output is :

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?

Run

pg_lsclusters

and see what port the server is running on.

Thanks in advance.
