如何杀死我所有的postgresql连接?
我试着耙db:下降，但我得到:
ERROR: database "database_name" is being accessed by other users
DETAIL: There are 1 other session(s) using the database.
我尝试过关闭我从ps -ef | grep postgres中看到的进程，但这也不起作用:
kill: kill 2358 failed: operation not permitted

在PG管理中，您可以断开您的服务器(右键单击服务器)&所有会话将在重新启动时断开

没有必要放弃。只需删除并重新创建公共模式。在大多数情况下，这有完全相同的效果。
namespace :db do
desc 'Clear the database'
task :clear_db => :environment do |t,args|
ActiveRecord::Base.establish_connection
ActiveRecord::Base.connection.tables.each do |table|
next if table == 'schema_migrations'
ActiveRecord::Base.connection.execute("TRUNCATE #{table}")
end
end
desc 'Delete all tables (but not the database)'
task :drop_schema => :environment do |t,args|
ActiveRecord::Base.establish_connection
ActiveRecord::Base.connection.execute("DROP SCHEMA public CASCADE")
ActiveRecord::Base.connection.execute("CREATE SCHEMA public")
ActiveRecord::Base.connection.execute("GRANT ALL ON SCHEMA public TO postgres")
ActiveRecord::Base.connection.execute("GRANT ALL ON SCHEMA public TO public")
ActiveRecord::Base.connection.execute("COMMENT ON SCHEMA public IS 'standard public schema'")
end
desc 'Recreate the database and seed'
task :redo_db => :environment do |t,args|
# Executes the dependencies, but only once
Rake::Task["db:drop_schema"].invoke
Rake::Task["db:migrate"].invoke
Rake::Task["db:migrate:status"].invoke
Rake::Task["db:structure:dump"].invoke
Rake::Task["db:seed"].invoke
end
end
我的工作如下:
sudo gitlab-ctl stop
sudo gitlab-ctl start gitaly
sudo gitlab-rake gitlab:setup [type yes and let it finish]
sudo gitlab-ctl start
我正在使用: gitlab_edition:“gitlab-ce” gitlab_version:“12.4.0-ce.0.el7”
MacOS，如果postgresql安装了brew:
brew services restart postgresql
删除postgresql会话/连接
退出postgres并重新启动。很简单，但每次对我都有效，而其他cli命令有时不能。
