PG::UndefinedTable: ERROR: relation "<name>" does not exist

I have looked through similar answers, but it didn't work for my question.
I use Windows 10 + Ubuntu 18.04 and try to change the database of a Rails project from SQLite3 to PostgreSQL. After I modified the Gemfile, executed the bundle and completed the modification of database.yml, I proceeded to $rails db:create.
Finally, I tried to do $rails db:migrate, and the following error occurred:

This is my database.yml

development:

I also tried to execute the $psql command, but the following error message appeared
psql: FATAL: database "keaton" does not exist
I really don't know what to do, please teach me, thank you

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
This problem occurs even if I drop the database, comment out specific fields like, for example, encrypted_password in migration file. I've also tried to reset migration, set it to development mode. I'm using Devise and trying to run this migration file. If anyone got any ideas of why or how this happens I'd appreciate some ideas to fix this issue.
Could this happen because of an error in a certain file?
Migration status:
database: fitnesshabbits_development
Status Migration ID Migration Name
--------------------------------------------------
up 20190227233216 Devise create users
down 20190301194540 Add devise to users

I think that you have add the same field in your two migrations.
I think that you have add encrypted_password in you AddDeviseToUsers migration.
Lock that in your migrations don't have field that are repeat.

Migration not working in Ruby On Rails

For some reason or another my Ruby on Rails application is telling me that it can't run migrations. I an unsure how to fix this. I created a table with no information by accident. I then tried to delete the migration file and the table that it created. When I try to run the migration command it gives me this error:
rails aborted!
Don't know how to build task 'db:migration' (see --tasks)

Can someone please help me fix this issue. I need to remove the existing table so that I can create the correct one. It won't populate my schema file.
This is the error that I get when I run rake db:migrate

Tasks: TOP => db:migrate
(See full trace by running task with --trace)

In addition to my comment suggesting you use rake db:migrate instead of rake db:migration:
I also suggest you look into rake db:rollback if you find you've made a mistake while generating your model/migration.

I believe you've used migration instead of migrate
rake db:migrate

Remove duplicate columns in rails migration

I am had Paperclip gem in my app then I removed it and I wanna add it back again. However, I am getting this error when I try to rake db:migrate:

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
When I ran rails c this is what I got:
2.3.0 :001 > Post.column_names
=> ["id", "title", "link", "description", "created_at", "updated_at", "user_id", "image_file_name", "image_content_type", "image_file_size", "image_updated_at", "cached_votes_total", "cached_votes_score", "cached_votes_up", "cached_votes_down", "cached_weighted_score", "cached_weighted_total", "cached_weighted_average", "image"]
I know that there is a way to remove the "image_file_name" duplication but I am not really aware of how to do so to my app. I did find some posts that are similar to my problem but nothing really solved it!

Because you deleted the migration for creating the column, and if you create a migration to delete it, it will cause error in other environment(production), as there is no column to be deleted at first place.
Assuming you haven't deploy the migration to production.
You can just drop the column directly in database console.
run rails dbconsole
and
ALTER TABLE posts DROP COLUMN image_file_name;

First of all, you should never just remove a migration. If you want to remove a field you should create a new migration for it.
You have 2 options now, or you can rake db:migration:reset that will recreate your entire database OR you can comment the content on this last migration, run rake db:migrate and after that you can uncomment it.

How to write a migration changing id to uuid

class ChangeIdtoUuiDforcarts < ActiveRecord::Migration
def change
rename_column :carts, :id, :uuid
change_column :carts, :uuid, 'using uuid::uuid'
end
end
I have tried the above migration, but it gives the following syntax error
-- rename_column(:carts, :id, :uuid)
-> 0.0032s
-- change_column(:carts, :uuid, "using uuid::uuid")
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
PG::SyntaxError: ERROR: syntax error at or near "using"
