So I set a Linux shell password on my newly auto created 'postgres'
system user which is what I use to login to the database as
'superuser'. Now I know my password for 'postgres' in the Linux shell
but I still don't understand what the database password is for
'postgres'. In MySQL there is a root shell user (obviously) and then
rather than 'postgres' for the database super user, there is a 'root'
database user and I can set that password individually from the
matching shell account.
So maybe I am still lost but it appears that the database user
'postgres' has a password unique to PostgreSQL, right?
postgres=# SELECT * from pg_user;
usename | usesysid | usecreatedb | usesuper | usecatupd | passwd |
valuntil | useconfig
----------+----------+-------------+----------+-----------+----------+----------+-----------
postgres | 10 | t | t | t | ******** |
|
carlos | 16384 | t | t | t | ******** |
|
Obviously there appears to be a specific password for both accounts
which I think are completely seperate from the Linux shell passwords,
right?
Secondly I am unable to find any information in the docs that show me
how to set just the user password for 'carlos'. In MySQL I would use:
SET PASSWORD FOR 'carlos'@'localhost' = PASSWORD('newpass');
