以下執行方式是linux系統的設定方式
安裝pgagent 於centos linux
yum install pgagent_91
在執行psql指令時要用postgres帳號做操作
登入帳號
su -l postgres
為資料庫安裝pgagent,這一步要注意,要確定將pgagent.sql安裝到正確的資料庫,
安裝pgagent到資料庫postgres
psql < /usr/share/pgagent_91-3.0.1/pgagent.sql
安裝pgagent到資料庫n5_data
psql -d n5_data < /usr/share/pgagent_91-3.0.1/pgagent.sql
pgagent.sql執行內容,會在該資料庫中建立所需要的資料表,建好後用PgAdminIII中的catalogs->pgAgent->Tables中看到
-bash-4.1$ psql -d n5_data < /usr/share/pgagent_91-3.0.1/pgagent.sql

以上只是為資料庫建立基本的環境,以上執行完時啟動PgAdminIII後,點選該資料庫會在tree中新增一個jobs的項目
可在該jobs中新增排程。
排程建立好後並不會執行,需要啟動pgagent的服務才會依jobs中的設定執行排程,以下指令要在root下操作
因為每個資料庫都建有自已的pgagent,所以在啟動服務的部分也要依不同的資料庫做啟動,指令如下
資料庫postgres啟動排程
pgagent hostaddr=localhost dbname=postgres user=postgres password=******
資料庫n5_data啟動排程
pgagent hostaddr=localhost dbname=n5_data user=postgres password=******
執行指令後若沒有錯誤代表啟動成功
可以用ps aux | grep pgagent做檢查
[root@db ~]# ps aux | grep pgagent
root 20774 0.0 0.0 229664 2688 ? S 17:27 0:00 pgagent hostaddr=localhost dbname=postgres user=postgres password=******
root 21028 0.0 0.0 78012 2292 ? S 17:32 0:00 pgagent hostaddr=localhost dbname=n5_data user=postgres password=******
root 22467 0.0 0.0 103232 856 pts/0 S+ 18:02 0:00 grep pgagent
[root@db ~]#
