CREATE USER(7)				   SQL Commands 			   CREATE USER(7)

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'

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.

   PARAMETERS
       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(7)].

       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  sup-
	      port  for  the  MD5  authentication mechanism that is needed to work with passwords
	      that are stored encrypted.

       CREATEDB

       NOCREATEDB
	      These clauses define a user's ability to create databases. If  CREATEDB  is  speci-
	      fied,  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 him-
	      self. 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.

DIAGNOSTICS
       CREATE USER
	      Message returned if the command completes successfully.

NOTES
       Use ALTER USER [alter_user(7)]  to  change  the	attributes  of	a  user,  and  DROP  USER
       [drop_user(7)]  to  remove  a  user.  Use  ALTER GROUP [alter_group(l)] to add the user to
       groups or remove the user from groups.  PostgreSQL includes a  program  createuser  [crea-
       teuser(1)]  that  has  the same functionality as this command (in fact, it calls this com-
       mand) but can be run from the command shell.

EXAMPLES
       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
       The  CREATE  USER statement is a PostgreSQL extension. The SQL standard leaves the defini-
       tion of users to the implementation.
