CREATE DATABASE northwind;

i’m getting an error creating database through pgAdmin

ERROR: source database “template1” is being accessed by other users
DETAIL: There is 1 other session using the database.
SQL state: 55006

Did you resolve it? If not, take a look at these:

Let me know if it is still an issue.
