First, switch to the postgres system user account and run the psql command as follows: $ sudo su - postgres To create a new database in PostgreSQL, you need to access the PostgreSQL database shell (psql) program. PostgreSQL Accepting Client Connections Creating Database in PostgreSQL If you have more than one data directory for the same PostgreSQL version you'll have to look at database size, check the command line of the running postgres from ps to see if it's data directory -D argument matches where you're editing, etc.After PostgreSQL installed, you can confirm that the PostgreSQL service is active, running and is enabled under systemd using the following systemctl commands: $ sudo systemctl is-active postgresqlДЄlso, confirm that the Postgresql server is ready to accept connections from clients as follows: $ sudo pg_isready (If pg_hba.conf is in /etc/, ignore this, it's the parent directory name instead). Then check the PG_VERSION file in the same directory to make sure it's the right PostgreSQL version if you have more than one.

On Mac and Linux something like sudo find / -type f -name pg_hba.conf will do. If you can't connect (Pg isn't running, or you need to edit pg_hba.conf to connect) you'll have to search the system for pg_hba.conf files. You can ask pg_wrapper, the Debian/Ubuntu multi-version Pg manager, where PostgreSQL is using the pg_lsclusters command from pg_wrapper.

You don't have to deal with hand-compiled-from-source Pg that someone's initdb'd a datadir for in their home dir, or an EnterpriseDB Pg install in /opt, etc.

If you're targeting specifically Ubuntu systems with PostgreSQL installed from Debian/Ubuntu packages it gets a little easier. Since pg_hba.conf will be inside the data directory (unless you're on Debian/Ubuntu or some derivative and using their packages). Yes, this is somewhat of a chicken-and-egg problem, in that if the user can't connect (say, after screwing up editing pg_hba.conf) you can't find pg_hba.conf in order to fix it.ДЄnother option is to look at the ps command's output and see if the postmaster data directory argument -D is visible there, e.g. This command must be run on a superuser session, so for shell scripting you might write something like: psql -t -P format=unaligned -c 'show hba_file' ДЄnd set the environment variables PGUSER, PGDATABASE, etc to ensure that the connection is right. What you want to do is ask PostgreSQL: SHOW hba_file You can't even rely on asking where the datadir is and parsing nf because an init script might passed a param like -c hba_file=/some/other/path when starting Pg. The only valid ways find pg_hba.conf is to ask a running PostgreSQL instance where it's pg_hba.conf is, or ask the sysadmin where it is. The standard location is pg_hba.conf within the data_directory of the database (which could be in /home, /var/lib/pgsql, /var/lib/postgresql//, /opt/postgres/, etc etc etc) but users and packagers can put it wherever they like. Pg_hba.conf can appear in many other places depending on how Pg was installed. It knows nothing about the active PostgreSQL instance(s) on the machine, only the binaries. Pg_config is for compliation information, to help extensions and client programs compile and link against PostgreSQL.
