CREATEUSER(1)

💖 CREATEUSER(1) — the createuser glow-up guide 💖

okay so real talk, this is the createuser page from the PostgreSQL 15.19 docs, and we're gonna make it make sense. bestie, grab a snack 🍓

✨ NAME ✨

createuser — define a new PostgreSQL user account 👑

---

✨ SYNOPSIS ✨

createuser [connection-option...] [option...] [username]

---

🦋 DESCRIPTION 🦋

createuser creates a new PostgreSQL user — or, more precisely, a role. lowkey fancy.

Only superusers and users with CREATEROLE privilege can create new users, so createuser must be invoked by someone who can connect as a superuser or as a user with CREATEROLE privilege. no random walk-ins, sorry 💅

If you want to create a role with the SUPERUSER, REPLICATION, or BYPASSRLS privilege, you must connect as a superuser — not merely with CREATEROLE privilege. Being a superuser implies the ability to bypass all access permission checks within the database, so superuser access should not be granted lightly. CREATEROLE also conveys very extensive privileges, so like… be careful, fr fr 🙈

createuser is a wrapper around the SQL command CREATE ROLE. There is no effective difference between creating users via this utility and via other methods for accessing the server. same energy, different packaging 🎀

---

🌸 OPTIONS 🌸

createuser accepts the following command-line arguments:

• username — the name of the PostgreSQL user to be created. This name must be different from all existing roles in this PostgreSQL installation. no dupes allowed, we don't do that here ✨
• -c number, --connection-limit=number — set a maximum number of connections for the new user. The default is to set no limit. go wild, or don't 💜
• -d, --createdb — the new user will be allowed to create databases.
• -D, --no-createdb — the new user will not be allowed to create databases. This is the default.
• -e, --echo — echo the commands that createuser generates and sends to the server. very "show your work" of it 👀
• -E, --encrypted — this option is obsolete but still accepted for backward compatibility. she's retired but she still shows up to the party 💀
• -g role, --role=role — indicates role to which this role will be added immediately as a new member. Multiple roles to which this role will be added as a member can be specified by writing multiple -g switches. stack 'em 🫶
• -i, --inherit — the new role will automatically inherit privileges of roles it is a member of. This is the default.
• -I, --no-inherit — the new role will not automatically inherit privileges of roles it is a member of.
• --interactive — prompt for the user name if none is specified on the command line, and also prompt for whichever of the options -d/-D, -r/-R, -s/-S is not specified on the command line. (This was the default behavior up to PostgreSQL 9.1.) retro icon behavior ⭐
• -l, --login — the new user will be allowed to log in (that is, the user name can be used as the initial session user identifier). This is the default.
• -L, --no-login — the new user will not be allowed to log in. (A role without login privilege is still useful as a means of managing database permissions.) permission-girlie era 🎀
• -P, --pwprompt — if given, createuser will issue a prompt for the password of the new user. This is not necessary if you do not plan on using password authentication.
• -r, --createrole — the new user will be allowed to create, alter, drop, comment on, change the security label for, and grant or revoke membership in other roles; that is, this user will have CREATEROLE privilege. See role creation for more details about what capabilities are conferred by this privilege. main character privilege energy 👑
• -R, --no-createrole — the new user will not be allowed to create new roles. This is the default.
• -s, --superuser — the new user will be a superuser. big power, handle with care 🔥
• -S, --no-superuser — the new user will not be a superuser. This is the default.
• -V, --version — print the createuser version and exit.
• --replication — the new user will have the REPLICATION privilege, which is described more fully in the documentation for CREATE ROLE (CREATE_ROLE(7)).
• --no-replication — the new user will not have the REPLICATION privilege, which is described more fully in the documentation for CREATE ROLE (CREATE_ROLE(7)).
• -?, --help — show help about createuser command line arguments, and exit. when in doubt, ask for help bestie 🫶

createuser also accepts the following command-line arguments for connection parameters:

• -h host, --host=host — specifies the host name of the machine on which the server is running. If the value begins with a slash, it is used as the directory for the Unix domain socket. cute little path moment 🦋
• -p port, --port=port — specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections.
• -U username, --username=username — user name to connect as (not the user name to create). read that twice, it trips everyone up 😭
• -w, --no-password — never issue a password prompt. If the server requires password authentication and a password is not available by other means such as a .pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user is present to enter a password. automation girlies rise 🌈
• -W, --password — force createuser to prompt for a password (for connecting to the server, not for the password of the new user).

This option is never essential, since createuser will automatically prompt for a password if the server demands password authentication. However, createuser will waste a connection attempt finding out that the server wants a password. In some cases it is worth typing -W to avoid the extra connection attempt. efficiency slay 💅

🌈 ENVIRONMENT 🌈

• PGHOST
• PGPORT
• PGUSER

— default connection parameters ✨

• PG_COLOR — specifies whether to use color in diagnostic messages. Possible values are always, auto and never. aesthetic diagnostics, we love to see it 🎨

This utility, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see Section 34.15).

---

🧚 DIAGNOSTICS 🧚

In case of difficulty, see CREATE ROLE (CREATE_ROLE(7)) and psql(1) for discussions of potential problems and error messages. The database server must be running at the targeted host. Also, any default connection settings and environment variables used by the libpq front-end library will apply. it's giving "did you check if it's plugged in" 😭

👑 EXAMPLES 👑

To create a user joe on the default database server:

$ createuser joe

To create a user joe on the default database server with prompting for some additional attributes:

$ createuser --interactive joe
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) n

To create the same user joe using the server on host eden, port 5000, with attributes explicitly specified, taking a look at the underlying command:

$ createuser -h eden -p 5000 -S -D -R -e joe
CREATE ROLE joe NOSUPERUSER NOCREATEDB NOCREATEROLE INHERIT LOGIN;

To create the user joe as a superuser, and assign a password immediately:

$ createuser -P -s -e joe
Enter password for new role: xyzzy
Enter it again: xyzzy
CREATE ROLE joe PASSWORD 'SCRAM-SHA-256$4096:44560wPMLfjqiAzyPDZ/eQ==$4CA054rZlSFEq8Z3FEhToBTa2X6KnWFxFkPwIbKoDe0=:L/nbSZRCjp6RhOhKK56GoR1zibCCSePKshCJ9lnl3yw=' SUPERUSER CREATEDB CREATEROLE INHERIT LOGIN;

In the above example, the new password isn't actually echoed when typed, but we show what was typed for clarity. As you see, the password is encrypted before it is sent to the client. 🔐 not me showing you my password… (it's xyzzy, it's fine, it's a demo)
