Thanks Matthias.
postgres@pc:/home/marco$ /usr/lib/postgresql/11/bin/initdb -D /usr/local/pgsql/data
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locales

CTYPE: en_GB.UTF-8
MESSAGES: en_GB.UTF-8

NUMERIC: C.UTF-8
TIME: C.UTF-8
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
/usr/lib/postgresql/11/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start
But now permission denied:
postgres@pc:/home/marco$ sudo /usr/lib/postgresql/11/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start
[sudo] password for postgres:
postgres is not in the sudoers file. This incident will be reported.
