AWS RDS PostgreSQL 表空间

Question

I created an AWS RDS postgres instance. When creating i was prompted to create user. There is no reason for creating tablespaces with location in AWS RDS? The reason is when creating a database i want the database to goto the tablespace i created. When i run the below command

CREATE USER test;

CREATE TABLESPACE test OWNER test LOCATION '/test_data';

CREATE DATABASE test WITH TEMPLATE = template0 ENCODING = 'UTF8' LC_COLLATE = 'C' LC_CTYPE = 'C' TABLESPACE = test;

ERROR:  permission denied for tablespace test

I logged into postgres using test_admin user to run the above commands. The test_admin is the account i created during the RDS instance provisioning. Is that the only account that i should be using above to create all of the DB objects from that point?

Answer 1

Do you want the owner of the database to be test as well? If so, add that into your CREATE DATABASE... . Otherwise, you'll probably need to give the test_admin user permission on the test tablespace before trying to create it.

Answer 2

Tablespaces in postgres RDS are located in /rdsdbdata/db/base/tablespace/

and I think this question has been answered here Create tablespace on PostgreSQL RDS
