Running an Ubuntu Server 20.04 (24 core, 64GB Ram)

New to Odoo.  Trying it out with standard downloaded Debian installer.

Fresh install of Odoo 13

Fresh install of Postgres SQL 12

I'm as far along at attempting to start Odoo, but it fails connecting to the database.

I am 100% certain the database is running and on the standard port.

The "odoo" user is created, and, though I read somewhere the default "odoo" user password is "odoo", I changed it due to this error.  The contents of my "odoo.conf" file is:

-----------------------------------------------

[options]
; This is the password that allows database operations:
; admin_passwd = admin
db_host = 127.0.0.1
db_port = 5432
db_user = odoo
db_password = *** OBFUSCATED ODOO PASSWORD FOR DB USER ***
;addons_path = /usr/lib/python3/dist-packages/odoo/addons

--------------------------------------------

Clearly, I've not exposed the db_password for the odoo user above, but I've been careful to verify.

In my potfresql pg_hba file, under the administrative login section, I have:

---------------------------------------------

# TYPE  DATABASE        USER            ADDRESS                 METHOD
local   all             postgres                                peer
# "local" is for Unix domain socket connections only
local   all             all                                     md5
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5

---------------------------------------------

So, I need help identifying why Odoo cannot start properly.
