split 命令可以將大型檔案切成小塊以適應檔案系統限制的單個檔案大小。

分割,每650M為一個檔案，試用於光盤備份

			
$ pg_dump dbname | split -b 650m - filename
			
			

合併，並且恢復到資料庫中。

			
$ createdb dbname
$ cat filename* | psql dbname
			
			

從 schema 中導出數據

				
pg_dump -h 192.168.1.242 -U user -s database -n schema > schema.sql	
			
			

導入目標資料庫
