Description: Not working: GRANT * TO GROUP *
Details:

Hello.

I am trying to assign connect and temporary privilages to a group and it is
not working. I think i am writing the SQL sentence correctly, but it doesn't
work.

db: a default empty database.
db_group: a group role.

I tried, using both the GUI and CLI:
GRANT CONNECT, TEMPORARY ON DATABASE db TO GROUP db_group;

But somehow the results was as if i had witten (even though there is no
db_group user):
GRANT CONNECT, TEMPORARY ON DATABASE db TO db_group;

Regards,

Alvaro.
