CREATE GROUP

Name

CREATE GROUP -- define a new user group

CREATE GROUP name [ [ WITH ] option [ ... ] ]  where option can be:       SYSID gid    | USER  username [, ...]

CREATE GROUP will create a new group in the database cluster. You must be a database superuser to use this command.

Use ALTER GROUP to change a group's membership, and DROP GROUP to remove a group.

name

The name of the group.

gid

The SYSID clause can be used to choose the PostgreSQL group ID of the new group. It is not necessary to do so, however.

If this is not specified, the highest assigned group ID plus one, starting at 1, will be used as default.

username

A list of users to include in the group. The users must already exist.

Create an empty group:

CREATE GROUP staff;

Create a group with members:

CREATE GROUP marketing WITH USER jonathan, david;

There is no CREATE GROUP statement in the SQL standard. Roles are similar in concept to groups.
