       initdb — initalize the database templates and primary directories

       initdb [-d ] [-n ] [-r directory ] [-t ] [-u username ] [-v ]

       Initdb sets up the initial template databases and is normally executed
       as part of the installation process.  The template database is created
       under the directory specified by the the environment variable PGDATA,
       or to a default specified at compile-time.  The template database is
       then vacuumed.

       Initdb is a shell script that invokes the backend server directly.
       Hence, it must be executed by the Postgres super-user.

       Initdb understands the following command-line options:

       -d     Print debugging output from the backend server.  This option
              generates a tremendous amount of information.  This option also
              turns off the final vacuuming step.

       -n     Run in “noclean” mode.  By default, initdb cleans up
              (recursively unlinks) the data directory if any error occurs,
              which also removes any core files left by the backend server.
              This option inhibits any tidying-up.

       -r directory
              Use the specified data directory.

       -t     Update template database only.

       -u username
              Run as the specified username.

       -v     Produce verbose output, printing messages stating where the
              directories are being created, etc.

              The location of global (shared) classes.

              The location of the template database.

              Command files used to generate the global and template
              databases, generated and installed by the initial compilation
