CREATE
NAME
  CREATE USER - define a new database user account

SYNOPSIS
  CREATE USER username [ [ WITH ] option [ ... ] ]

  where option can be:

	    SYSID uid
	  | [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
	  | CREATEDB | NOCREATEDB
	  | CREATEUSER | NOCREATEUSER
	  | IN GROUP groupname [, ...]
	  | VALID UNTIL 'abstime'

  INPUTS

  username
       The name of the user.

  uid  The SYSID clause can be used to choose the PostgreSQL user id of the
       user that is being created. It is not at all necessary that those
       match the UNIX user ids, but some people choose to keep the numbers
       the same.

       If this is not specified, the highest assigned user id plus one (with
       a minimum of 100) will be used as default.

  password
       Sets the user's password. If you do not plan to use password
       authentication you can omit this option, but the user won't be able to
       connect to a password-authenticated server.  The password can be set
       or changed later, using ALTER USER [alter_user(5)].

  ENCRYPTED

  UNENCRYPTED
       These keywords control whether the password is stored encrypted in
       pg_shadow. (If neither is specified, the default behavior is
       determined by the PASSWORD_ENCRYPTION server parameter.) If the
       presented string is already in MD5-encrypted format, then it is stored
       as-is, regardless of whether ENCRYPTED or UNENCRYPTED is specified.
       This allows reloading of encrypted passwords during dump/restore.

       See the chapter on client authentication in the Administrator's Guide
       for details on how to set up authentication mechanisms. Note that
       older clients may lack support for the MD5 authentication mechanism
       that's needed to work with passwords that are stored encrypted.

  CREATEDB

  NOCREATEDB
       These clauses define a user's ability to create databases.  If
       CREATEDB is specified, the user being defined will be allowed to
       create his own databases. Using NOCREATEDB will deny a user the
       ability to create databases. If this clause is omitted, NOCREATEDB is
       used by default.

  CREATEUSER

  NOCREATEUSER
       These clauses determine whether a user will be permitted to create new
       users himself. This option will also make the user a superuser who can
       override all access restrictions.  Omitting this clause will set the
       user's value of this attribute to be NOCREATEUSER.

  groupname
       A name of a group into which to insert the user as a new member.
       Multiple group names may be listed.

  abstime
       The VALID UNTIL clause sets an absolute time after which the user's
       password is no longer valid. If this clause is omitted the login will
       be valid for all time.

  OUTPUTS

  CREATE USER
       Message returned if the command completes successfully.

DESCRIPTION
  CREATE USER will add a new user to an instance of PostgreSQL. Refer to the
  administrator's guide for information about managing users and
  authentication.  You must be a database superuser to use this command.

  Use ALTER USER [alter_user(5)] to change a user's password and privileges,
  and DROP USER [drop_user(5)] to remove a user.  Use ALTER GROUP
  [alter_group(5)] to add or remove the user from other groups.	 PostgreSQL
  comes with a script createuser [createuser(1)] which has the same
  functionality as this command (in fact, it calls this command) but can be
  run from the command shell.

USAGE
  Create a user with no password:

  CREATE USER jonathan

  Create a user with a password:

  CREATE USER davide WITH PASSWORD 'jw8s0F4';

  Create a user with a password, whose account is valid until the end of
  2001.	 Note that after one second has ticked in 2002, the account is not
  valid:

  CREATE USER miriam WITH PASSWORD 'jw8s0F4' VALID UNTIL 'Jan 1 2002';

  Create an account where the user can create databases:

  CREATE USER manuel WITH PASSWORD 'jw8s0F4' CREATEDB;

COMPATIBILITY
  SQL92

  There is no CREATE USER statement in SQL92.
