Hello!

I'm new in this group and I would like to solve one problem.

I've just installed on my Debian machine PostgreSQL from source files.
Everything was compiled correctly etc. Now when I'm logged in as
Postgres user i create a new one:

createuser jonash

but when I try to switch on him by:

su jonash

The info appears:
Unknown ID: jonash

Where is the problem?

Best regards!

That means, jonash is a user you might use to connect to the database, but
not to log into your system.

The problem is, 'createuser' creates database accounts. You must use
'adduser' for the system user.

Roland.

Well, I know about that a that's why I've also create a system user.
But even I've the system user "jonash" when I try:

postgres:$ su jonash
Password:

and second later it appears:
Password: incorrect password

Why?
