Description:

Hi everyone.
I have created tablespace.

sudo mkdir /tbs_data
sudo chown -R postgres:postgres /tbs_data
su - postgres
create tablespace tbs_data location ‘/tbs_data’;

Then I have create database and tables on that tablespace.

create database gescom_bis tablespace tbs_data;
\c gescom_bis;
SET default_tablespace = 'tbs_data';
create table voiture_bis (num int) tablespace tbs_data;

But when I run this the following query I have ans empty (blank result)

select tablespace from pg_tables where tablename='voiture_bis';

hence the tablespace name is not displayed.

But went I run the following query, everythins seams to work.

select oid from pg_database where datname = 'gescom_bis';
select relfilenode from pg_class where relname = 'voiture_bis';

Best ragrd.
