The database cluster will be initialized with locale "C.UTF-8". This user must also own the server process. The files belonging to this database system will be owned by user "postgres". Many lines should now appear on the screen with several ending by. $ initdb -locale=C.UTF-8 -encoding=UTF8 -D /var/lib/postgres/data -data-checksums For more options, see initdb -help and official documentation.(Once the database is up, you can check if it is enabled with $ psql -c "SHOW data_checksums".) Read #Enable data checksumming for more information. If your data directory resides on a file system without data checksumming, you may wish to enable PostgreSQL's built-in checksumming for increased integrity guarantees - add the -data-checksums argument to do so.(Once the database is up, you can check which values were used with $ psql -l.)
If this is not what you want, you can override the defaults using -locale= locale (where locale is to be chosen amongst the system's available locales) and -encoding= encoding (which must match the chosen locale). By default, the locale and the encoding for the database cluster are derived from your current environment (using $LANG value).initdb accepts a number of extra arguments: Where -D is the default location where the database cluster must be stored (see #Change default data directory if you want to use a different one). If you have sudo and are in sudoers: $ sudo -iu postgresīefore PostgreSQL can function correctly, the database cluster must be initialized:.You can switch to the PostgreSQL user by executing the following command: Note: Commands that should be run as the postgres user are prefixed by $ in this article. 8.5 Failing to start a PostgreSQL server with the older version of the database while upgrading to the newer version with extensions.
