Hi, I'm trying to deploy odoo18 on heroku, I've added a Procfile on the root of odoo with this line :

web: python3 odoo-bin --config=odoo.conf

then on my root I created a odoo.conf file like this : 

[options]
db_user = my postgres db user
db_password = my postgres passw
db_host =my db host
db_port =5432
db_name = my dynamo
addons-path=addons

but I keep getting this error when I run odoo: 

2025-02-04T17:10:11.215872+00:00 app[web.1]: psycopg2.OperationalError: connection to server at "(mydbhost)" (mydbhostip), port 5432 failed: FATAL:  permission denied for database "postgres"

2025-02-04T17:10:11.215873+00:00 app[web.1]:

2025-02-04T17:10:11.391071+00:00 heroku[web.1]: State changed from starting to crashed

how can I fix this? thx
