在 Windows 環境用排程進行 PostgreSQL database 的備份與維護

bestlong

1)  建立一個目錄 %APPDATA%\postgresql
在我的環境中為 C:\Documents and Settings\bestlong\Application Data\postgresql

2)  建立一個檔案 %APPDATA%\postgresql\pgpass.conf
可使用文字編輯程式如 Notepad

3)  輸入必要的設定在 %APPDATA%\postgresql\pgpass.conf
內容如下行
localhost:*:myDBname:myUserName:myPassword

4)  建立批次檔來執行備份或維護作業, 指令如下:
"C:\Program Files\PostgreSQL\8.0\bin\psql" -h localhost -d myDBname -U myUserName -f Name-Of-File-With-Maintenance-Commands
"C:\Program Files\PostgreSQL\8.0\bin\pg_dump" -f Name-Of-My-Dump-File -Fc -Z 9 -h localhost -U myUserName myDBname

5)  Use the task scheduler to run your newly created batch file whenever you'd like it to run

I actually run my batch file every night.  My DB has no activity during the night, so I run my maintenance then.

Name-Of-File-With-Maintenance-Commands contains SQL to refresh a materialized view and do a vacuum full analyze
