Kill a postgresql session/connection

Question

How can I kill all my postgresql connections?

I\'m trying a rake db:drop but I get:

ERROR:  database \"database_name\" is being accessed         


        

Answer 1

For me worked the following:

sudo gitlab-ctl stop
sudo gitlab-ctl start gitaly
sudo gitlab-rake gitlab:setup [type yes and let it finish]
sudo gitlab-ctl start

I am using:
gitlab_edition: "gitlab-ce"
gitlab_version: '12.4.0-ce.0.el7'
