Re: Re: Re: How to use createdb command with newly created user?

Thank you for your advice.

.pgpass file would help a lot.

I recently started to writing SQL on PostgreSQL.

I think I should use capitial letters as sparingly as possible for identifiers.

Better to run now, and save yourself hassle in the future:

ALTER ROLE "Baba" RENAME TO baba;

Also, use a .pgpass file: https://www.postgresql.org/docs/14/libpq-pgpass.html

Thank you! You are right!

After putting quotes around the username, it works!

Hi,

I tried to create a user with CREATEDB permission.

Then I wanted to run command line tool `createdb` with this newly created user.

So I ran SQL first to create a user:

```

CREATE USER Baba WITH PASSWORD 'xxx' CREATEDB;

```

Then I run the following command on PowerShell on Windows 10:

```

 createdb -U Baba -W test_db

```

But no mater how I tried, the password always failed.

If I specify the user as postgres, the defaut user, everything works fine.

```

createdb -U postgres -W test_db_1

```

Do you have any suggestions?

You named the user "baba" all lower-case but your createdb command uses Baba and in the OS the case-folding of identifiers does not happen.  Baba != baba  is your issue.
