CREATE GROUP name [ [ WITH ] option [ ... ] ] where option can be: SYSID gid | USER username [, ...]
CREATE GROUP will create a new group of users. You must be a database superuser to use this command.
Note that both users and groups are defined at the database cluster level, and so are valid in all databases in the cluster.
The name of the group.
The SYSID clause can be used to choose the PostgreSQL group ID of the new group. This is normally not necessary, but may be useful if you need to recreate a group referenced in the permissions of some object.
If this is not specified, the highest assigned group ID plus one (with a minimum of 100) will be used as default.
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.
