PostgreSQL中的表空间是基本目录之外的附加数据区域,此功能已在版本8.0中实现。 初始化数据库后默认的表空间有pg_default、pg_global。 pg_global表空间的物理文件位置在数据目录的global目录中,它用来保存系统表。 pg_default表空间的物理文件位置在数据目录的base子目录中,是template0和template1数据库的默认表空间。
由于CREATE DATABASE dbname并没有指明数据库模板,所以系统将默认克隆template1数据库,得到新的数据库dbname。(By default, the new database will be created by cloning the standard system database template1). 而template1数据库的默认表空间是pg_default,这个表空间是在数据库初始化时创建的,所以所有template1...
