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

关于运行进程的所有信息:
SELECT *, pg_terminate_backend(pid)
FROM pg_stat_activity
WHERE pid <> pg_backend_pid()
AND datname = 'my_database_name';
其他回答
也许只是重启postgres => sudo服务postgresql重启
我使用下面的rake任务来覆盖Rails drop_database方法。
lib / database.rake
require 'active_record/connection_adapters/postgresql_adapter'
module ActiveRecord
module ConnectionAdapters
class PostgreSQLAdapter < AbstractAdapter
def drop_database(name)
raise "Nah, I won't drop the production database" if Rails.env.production?
execute <<-SQL
UPDATE pg_catalog.pg_database
SET datallowconn=false WHERE datname='#{name}'
SQL
execute <<-SQL
SELECT pg_terminate_backend(pg_stat_activity.pid)
FROM pg_stat_activity
WHERE pg_stat_activity.datname = '#{name}';
SQL
execute "DROP DATABASE IF EXISTS #{quote_table_name(name)}"
end
end
end
end
编辑:这是Postgresql 9.2+
OSX, Postgres 9.2(已安装自制程序)
$ launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
$ pg_ctl restart -D /usr/local/var/postgres
$ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
如果你的datadir在其他地方，你可以通过检查ps aux | grep postgres的输出来找到它
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
