CREATE USER name [ [ WITH ] option [ ... ] ]
where option can be:
SYSID uid
| [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
| CREATEDB | NOCREATEDB
| CREATEUSER | NOCREATEUSER
| IN GROUP groupname [, ...]
| VALID UNTIL 'abstime' CREATE USER adds a new user to an EnterpriseDB database cluster. Refer to Chapter 22 and Chapter 24 for information about managing users and authentication. You must be a database superuser to use this command.
The name of the user.
The SYSID clause can be used to choose the EnterpriseDB user ID of the user that is being created. This is normally not necessary, but may be useful if you need to recreate the owner of an orphaned object.
If this is not specified, the highest assigned user ID plus one (with a minimum of 100) will be used as default.
Sets the user's password. If you do not plan to use password authentication you can omit this option, but then the user won't be able to connect if you decide to switch to password authentication. The password can be set or changed later, using ALTER USER.
These key words control whether the password is stored encrypted in the system catalogs. (If neither is specified, the default behavior is determined by the configuration parameter password_encryption.) If the presented password string is already in MD5-encrypted format, then it is stored encrypted as-is, regardless of whether ENCRYPTED or UNENCRYPTED is specified (since the system cannot decrypt the specified encrypted password string). This allows reloading of encrypted passwords during dump/restore.
Note that older clients may lack support for the MD5 authentication mechanism that is needed to work with passwords that are stored encrypted.
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.
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.
A name of a group into which to insert the user as a new member. Multiple group names may be listed.
The VALID UNTIL clause sets an absolute time after which the user's password is no longer valid.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.
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 that is valid until the end of 2004. After one second has ticked in 2005, the password is no longer valid.
CREATE USER miriam WITH PASSWORD 'jw8s0F4' VALID UNTIL '2005-01-01';
Create an account where the user can create databases:
CREATE USER manuel WITH PASSWORD 'jw8s0F4' CREATEDB;
