django/postgres error:'database XX does not exist' - django

Question

I created a database using pgAdmin GUI tool to use with postgres for my django project. There are only two databases in pgAdmin, the default 'postgres' db you get out of the box with pgAdmin, and my new database, dbfunk.
I'm using django and added postgres as my database and gave the necessary info in settings.
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'dbfunk',
'USER': 'postgres',
'PASSWORD': 'XXXXXX',
'HOST': 'localhost'
}
}
But when I run
python manage.py makemigrations
it gives the error, the database 'dbfunk' does not exist, even though it's in both settings.py in Django and added in pgAdmin. The full text of the error is:
django.db.utils.OperationalError: FATAL: database "dbfunk" does not exist
I've installed the adaptor psycopg2. I also tried 'ENGINE': 'django.db.backends.postgresql_psycopg2', in Settings.py but this didn't make any difference.
Is there something else I am missing?
When I ran the command psql \u it is only showing the postgres database there also, and not this new database 'dbfunk'.
I don't know if this helps, but upon installing postgres, I was given 5433 in the prompt as the port number.
UPDATE: I just ran createdb dbfunk from command line and that seems to have created it as I can now run python manage.py makemigrations. But why did I need to do that when I had already done this in pgAdmin? That is, why did I have to create it twice? Is this usual?
UPDATE2: Sadly the database dbfunk that I created from command line using createdb and the dbfunk in pgAdmin are not synchronised and migrations won't carry over, such that I don't see the tables for the django models in pgAdmin.
I installed Postgres initially using Homebrew, and pgAdmin separately but then it didn't provide the default server/database on pgAdmin so I deleted pgAdmin, and uninstalled Postgres, and then downloaded Postgres from the website instead, and it seems that installs pgAdmin alongside it because then when I opened pgAdmin it had the default server/db postgres. I am on macOS, 10.14.6.
When I check ports on 5432 I get this:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
postgres 16337 me 5u IPv4 0x7560dce8e7fXXXX 0t0 TCP localhost:postgresql (LISTEN)
postgres 16337 me 6u IPv6 0x7560dce8d2XXXXX 0t0 TCP localhost:postgresql (LISTEN)
And on 5433 there are more entries:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
postgres 16809 postgres 4u IPv6 0x7560dce8e883ed93 0t0 TCP *:pyrrho (LISTEN)

For starters you did not specify PORT in DATABASES. The default port for postgres is 5432, so if your database cluster that contained dbfunk was listening on port 5433 then Django would not find it. My guess is you have two instances of postgres running, one on port 5432 and the other on 5433. When you did createdb dbfunk I'm guessing you again did not specify a port and the database was created in the cluster listening on 5432. Now python manage.py makemigrations could find it using the settings in DATABASES.
