Name | Owner | Encoding | Access privileges
-----------+---------+----------+-------------------
postgres | gpadmin | UTF8 |
template0 | gpadmin | UTF8 |
template1 | gpadmin | UTF8 |
(3 rows)
[gpadmin@test1 ~]$ createdb gptest
[gpadmin@test1 ~]$ psql -l
List of databases
Name | Owner | Encoding | Access privileges
-----------+---------+----------+-------------------
gptest | gpadmin | UTF8 |
postgres | gpadmin | UTF8 |
