Access privileges

Hello,
Can you please describe the  " =Tc/postgres + postgres=CTc/postgres  +confluence=CTc/postgres".  I want to give the same permissions to the different user on a new database.


                               List of databases
    Name    |  Owner   | Encoding | Collate |  Ctype  |    Access privileges
------------+----------+----------+---------+---------+-------------------------
confluence | postgres | UTF8     | C       | C           | =Tc/postgres           +
                                                                           | postgres=CTc/postgres  +
                                                                           | confluence=CTc/postgres

Thanks,
