POSTGRESQL-SETUP(1) Postgresql RPM-dist manual POSTGRESQL-SETUP(1)NAME
postgresql-setup - manual page for postgresql-setup 9.2.7
SYNOPSIS
postgresql-setup {initdb|upgrade} [SERVICE_NAME]
DESCRIPTION
Script is aimed to help sysadmin with basic database cluster administration.
The SERVICE_NAME is used for selection of proper unit configuration file; For more info and howto/when use this script please look at the
docu file /usr/share/doc/postgresql-9.2.7/README.rpm-dist. The 'postgresql' string is used when no SERVICE_NAME is explicitly passed.
Available operation mode:
initdb Create a new PostgreSQL database cluster. This is usually the first action you perform after PostgreSQL server installation.
upgrade
Upgrade PostgreSQL database cluster to be usable with new server. Use this if you upgraded your PostgreSQL server to newer major
version (currently from 8.4 to 9.2).
ENVIRONMENT
PGSETUP_INITDB_OPTIONS
Options carried by this variable are passed to subsequent call of `initdb` binary (see man initdb(1)). This variable is used also
during 'upgrade' mode because the new cluster is actually re-initialized from the old one.
PGSETUP_PGUPGRADE_OPTIONS
Options in this variable are passed next to the subsequent call of `pg_upgrade`. For more info about possible options please look
at man pg_upgrade(1).
PGSETUP_DEBUG
Set to '1' if you want to see debugging output.

initdb - create a new PostgreSQL database cluster
SYNOPSIS
initdb [ options... ] --pgdata | -D directory
DESCRIPTION
initdb creates a new PostgreSQL database cluster (or database system). A database cluster is a collection of databases that are managed by
a single server instance.
Creating a database system consists of creating the directories in which the database data will live, generating the shared catalog tables
(tables that belong to the whole cluster rather than to any particular database), and creating the template1 database. When you create a
new database, everything in the template1 database is copied. It contains catalog tables filled in for things like the built-in types.
initdb initializes the database cluster's default locale and character set encoding. Some locale categories are fixed for the lifetime of
the cluster, so it is important to make the right choice when running initdb. Other locale categories can be changed later when the server
is started. initdb will write those locale settings into the postgresql.conf configuration file so they are the default, but they can be
changed by editing that file. To set the locale that initdb uses, see the description of the --locale option. The character set encoding
can be set separately for each database as it is created. initdb determines the encoding for the template1 database, which will serve as
the default for all other databases. To alter the default encoding use the --encoding option.
initdb must be run as the user that will own the server process, because the server needs to have access to the files and directories that
initdb creates. Since the server may not be run as root, you must not run initdb as root either. (It will in fact refuse to do so.)
Although initdb will attempt to create the specified data directory, often it won't have permission to do so, since the parent of the
desired data directory is often a root-owned directory. To set up an arrangement like this, create an empty data directory as root, then
use chown to hand over ownership of that directory to the database user account, then su to become the database user, and finally run
initdb as the database user.
OPTIONS -D directory
--pgdata=directory
This option specifies the directory where the database system should be stored. This is the only information required by initdb, but
you can avoid writing it by setting the PGDATA environment variable, which can be convenient since the database server (postmaster)
can find the database directory later by the same variable.
-E encoding
--encoding=encoding
Selects the encoding of the template database. This will also be the default encoding of any database you create later, unless you
override it there. To use the encoding feature, you must have enabled it at build time, at which time you also select the default
for this option.
--locale=locale
Sets the default locale for the database cluster. If this option is not specified, the locale is inherited from the environment that
initdb runs in.
--lc-collate=locale
--lc-ctype=locale
--lc-messages=locale
--lc-monetary=locale
--lc-numeric=locale
--lc-time=locale
Like --locale, but only sets the locale in the specified category.
-U username
--username=username
Selects the user name of the database superuser. This defaults to the name of the effective user running initdb. It is really not
important what the superuser's name is, but one might choose to keep the customary name postgres, even if the operating system
user's name is different.
-W
--pwprompt
Makes initdb prompt for a password to give the database superuser. If you don't plan on using password authentication, this is not
important. Otherwise you won't be able to use password authentication until you have a password set up.
Other, less commonly used, parameters are also available:
-d
--debug
Print debugging output from the bootstrap backend and a few other messages of lesser interest for the general public. The bootstrap
backend is the program initdb uses to create the catalog tables. This option generates a tremendous amount of extremely boring out-
put.
-L directory
Specifies where initdb should find its input files to initialize the database system. This is normally not necessary. You will be
told if you need to specify their location explicitly.
-n
--noclean
By default, when initdb determines that an error prevented it from completely creating the database system, it removes any files it
may have created before discovering that it can't finish the job. This option inhibits tidying-up and is thus useful for debugging.
ENVIRONMENT
PGDATA Specifies the directory where the database system is to be stored; may be overridden using the -D option.
