Stop restoring backup in pgAdmin I am currently restoring a database and I tried to restore the database three times. The third time I succeeded but unfortunately it seems that the other two attempts at restoring the database are still running but never finish. 

I have these two blue windows on the pgAdmin screen which I can not remove or stop executing. I tried a lot of things, I even uninstalled PostgreSQL two times but the restoring windows appeared again. 

I am using Windows 8 and PostgreSQL 9.6.
I had the same problem and this helped me to solve it:

SQL command to clean job queue in pgAdmin 4

I just had to uninstall pgAdmin, delete all the files on C:Program Files directory and in App Data directory, as well.
