Rails - switching my rails app DB from sqlite3 to postgresql - ruby-on-rails

Question

I've create a RoR application with default database sqlite3. but the problem is sqlite3 is supported on heroku (deploying my app on cloud).
It's been whole day but i can't be able to connect my rails app to postgresql.
This is the steps I've followed till now to connect my app to postgresql
Replace: gem 'sqlite3', '~> 1.4'
with: gem 'pg'
then: bundle install
successfully install all the gems
after that convert my db to postgresql
conflict config/database.yml
Overwrite D:/New folder/amazon-product/config/database.yml? (enter "h" for help) [Ynaqdhm]
force config/database.yml
gsub Gemfile
gsub Gemfile
in that it's overwrite my existing database.yml file to postgresql
after that when i enter command
rake db:create db:migrate
it giving me the error
rails db:create db:migrate
rake aborted!

# If the connection URL is provided in the special DATABASE_URL environment

I've already installed postgresql also create a new database table called 'details'
hierarchy of pgadmin 4
server --> postgresql 14 --> databases(2) --> postgres, details(which i want to use)
