Hi,
I am new to this list and reaching out because I am having troubles setting up a local PostgreSQL database on my laptop. Maybe, as a preamble, I should say that I am pretty much a novice trying to teach myself and get practical experience about database and SQL queries (I have some general idea about relational DB structure and operation but no actual experience creating a DB or writing SQL queries).
Some background about my setup:
- OS: my laptop runs Linux Mint 19.1 (a flavor of ubuntu 18.04); psql 12.1 was installed along with pgadmin 4. There is a single user (ie, sebastien) on this machine and the group postgres exists.
- database: I have successfully created the new superuser sebastien
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------------------+-----------
postgres | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
sebastien | Superuser, Create DB +| {}
| Password valid until infinity |
I have also successfully created a database (sebastien) for the new superuser sebastien, and a schema (test) within this database.
Now, I would like to assign a particular disk location for the tablespace used by this database but I am getting all kinds of errors apparently linked to folder permissions.
The location is /home/sebastien/data/pgdata96_sebastien has the following properties:
/home/sebastien/data $ ls -l
drwxr-xr-x 2 sebastien postgres 4096 Nov 19 09:14 pgdata96_sebastien
Starting psql as sebastien, I tried the following requests and got the following errors:
sebastien=# CREATE TABLESPACE sebdata LOCATION '/home/sebastien/data/pgdata96_sebastien';
ERROR: could not set permissions on directory "/home/sebastien/data/pgdata96_sebastien": Permission denied
sebastien=# ALTER DATABASE sebastien set TABLESPACE '/home/sebastien/data/pgdata96_sebastien';
ERROR: syntax error at or near "'/home/sebastien/data/pgdata96_sebastien'"
LINE 1: ALTER DATABASE sebastien set TABLESPACE '/home/sebastien/dat...

The manual states "The location must be an existing, empty directory that is owned by the PostgreSQL operating system user." So, I am not sure what I am doing wrong. Web searches ran on these error messages did not enlighten me more...
I would greatly appreciated any pointers to reference material on these issues or advises on how to approach this.
Thank you in advance for your time.
