推荐答案
我没有找到有关此的RDS文档，但是显然Postgres表空间可以在RDS上正常工作.您没有直接访问RDS使用的基础EBS卷的权限，但是如果您尝试使用某个任意目录的CREATE TABLESPACE命令:
I didn't find RDS documentation about this, but apparently Postgres tablespaces work fine on RDS. You don't have direct access to the underlying EBS volume that RDS is using, but if you try a CREATE TABLESPACE command with some arbitrary directory:
CREATE TABLESPACE测试空间位置'/foo/bar/baz';
您可以看到表空间的创建是这样的:mydb =>\D b表空间列表姓名|业主|位置
------------ + ------------ + -------------------------------------------pg_default |rdsadmin |pg_global |rdsadmin |测试空间|db_user |/rdsdbdata/db/base/tablespace/foo/bar/baz(3列)
You can see that the tablespace gets created like so:
mydb=> \db
List of tablespaces
Name | Owner | Location
------------+------------+-------------------------------------------
pg_default | rdsadmin |
pg_global | rdsadmin |
testspace | db_user | /rdsdbdata/db/base/tablespace/foo/bar/baz
(3 rows)
您应该能够在该表空间中创建表:mydb =>CREATE TABLE test(int)TABLESPACE测试空间；创建表
And you should be able to create tables in that tablespace just fine:
mydb=> CREATE TABLE test (a int) TABLESPACE testspace ;
CREATE TABLE
