本地备份

			
pg_dump --compress=9 --file=/backup/mydb.sql.gz mydb
			
			

Backup

			
pg_dump -i -h localhost -p 5432 -U user -Fc -c -f "your_db.backup" your_db
			
			

Restore

			
pg_restore -i -h localhost -p 5432 -U user -d your_db -v -c -Fc "your_db.backup"
			
			

导入

\i file.backup

			
postgres=# \i /home/neo/woodart.backup
			
			

			
pg_dump -h [host] -U [dbuser] -s [dbname] -n [schema] > [file path]		
			
			

local -> remote

			
set PG_HOME="C:\Program Files\PostgreSQL\8.1\bin"
%PG_HOME%\pg_dump.exe -i -h localhost -p 5432 -U woodart -Fc -c -f "woodart.backup" woodart
%PG_HOME%\pg_restore.exe -i -h woodart.8800.org -p 5432 -U woodart -d woodart -v -c -Fc "woodart.backup"
			
			

split 命令可以将大型文件切成小块以适应文件系统限制的单个文件大小。

分割,每650M为一个文件，试用于光盘备份

			
$ pg_dump dbname | split -b 650m - filename
			
			

合并，并且恢复到数据库中。

			
$ createdb dbname
$ cat filename* | psql dbname
			
			

从 schema 中导出数据

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

导入目标数据库

			
psql -U user -d your-db -f schema.sql
