"GRANT on Roles" supports multiple options

(resending with correct formatting)

Hi!

In the documentation of the GRANT[1] command, the Synopsis for "GRANT on Roles" command is incomplete. Quoting from the current docs:

GRANT role_name [, ...] TO role_specification [, ...]
[ WITH { ADMIN | INHERIT | SET } { OPTION | TRUE | FALSE } ]
[ GRANTED BY role_specification ]

The "GRANT on Roles" command is documented as if it expects a single option after "WITH", but it actually supports multiple options, separated by comma, e.g.

GRANT created_user TO creating_user WITH ADMIN TRUE, SET FALSE, INHERIT FALSE

The example is taken from section "21.2. Role Attributes"[2] of the documentation.

More examples can be found by searching the codebase:

git grep -Pi '\bGRANT\b.+\bTO\b.+,\s*(ADMIN|INHERIT|SET)\s+\w+'

The parser is implemented here:

src/backend/commands/user.c:1480:GrantRole(ParseState *pstate, GrantRoleStmt *stmt)

The documentation is to be corrected for v16, v17, and later versions.
