CREATE GROUP -- Creates a new group
CREATE GROUP name
[ WITH [ SYSID gid ]
[ USER username [, ...] ] ]
If this is not specified, the highest assigned group id plus one, starting at 1, will be used as default.
CREATE GROUP will create a new group in the database installation. Refer to the administrator's guide for information about using groups for authentication. 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.
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 SQL92. Roles are similar in concept to groups.
