default_tablespace
Hi Hackers,
After reviewing docs and searching web
cannot find out how to determine the default tablespace
of a user?
Like:
select spcname from blab where roloid = 1111;
Is this possible?
Thank you for your time.

It doesn't appear to me that default tablespaces are assigned to a user, they're
assigned to a database.
A user can set the variable default_tablespace in their session to over-ride the
database default, but that wouldn't be stored anywhere in the database (it's a client
variable).
you can find the OID for the default tablespace for a specific database in pg_database.

You can, however, do ALTER USER <user> SET default_tablespace=<whatever>, which will
cause default_tablespace to be set automatically upon login for that user.
I don't know of the top of my head how we store that in the system catalogs, though.
You'll have to check the documentation to find that out...

oh, you're right. my mistake.
and it looks like it's stored in useconfig in pg_user.
select * from pg_user where usename = 'david.kerr';
usename | usesysid | usecreatedb | usesuper | usecatupd | passwd | valuntil | useconfig
------------+----------+-------------+----------+-----------+----------+----------+---------------------------
david.kerr | 16482 | f | t | t | ******** | | {default_tablespace=test}

It's in pg_db_role_settings.
