Обсуждение: public schema owner for newly created database

Hello all,

I usually create new databases with an explicit owner which is the "application user" that is used by the application
toconnect to the database. 

I recently noticed when I do the following:

postgres=# create user arthur identified by 'secret';
postgres=# create database guide owner = arthur;

Then when running \l I do see that the new database is owned by arthur.

However wenn I connect to the database and use \dn I see that the public schema is owned by "postgres" (the user that
wasused to create the database). 

Due to the default privileges on the public schema this isn't really a problem and I can always change the owner for
theschema anyway. 

But I would have expected the owner of the database to be the owner of any "object" that is created during database
initialization. 

Do I have a wrong assumption here?


Regards
Thomas

It seems you do. See:

Ah, thanks. That somehow escaped me.

As far as I know, objects in the database are not created during database
initialization, but they are copied from the template database.
So if "public" is owned by "postgres" in the template database, it will be
the same way in the new database.
