postgres: db:create should not fail if the database does exist

[ledenis]

What you are doing?

To reproduce:

Launch a postgres database:

docker run -e POSTGRES_PASSWORD=password -p 5432:5432 postgres:11

Create a directory with this package.json:

{
  "name": "sequelize-test",
  "scripts": {
    "db:create": "sequelize db:create --url 'postgres://postgres:password@localhost:5432/database'"
  },
  "dependencies": {
    "pg": "8.11.3",
    "sequelize": "6.32.1",
    "sequelize-cli": "6.6.1"
  }
}

Then run:

$ npm i
$ npm run db:create

> db:create
> sequelize db:create --url 'postgres://postgres:password@localhost:5432/database'


Sequelize CLI [Node: 18.16.1, CLI: 6.6.1, ORM: 6.32.1]

Parsed url postgres://postgres:*****@localhost:5432/database
Database database created.

$ npm run db:create

> db:create
> sequelize db:create --url 'postgres://postgres:password@localhost:5432/database'


Sequelize CLI [Node: 18.16.1, CLI: 6.6.1, ORM: 6.32.1]

Parsed url postgres://postgres:*****@localhost:5432/database

ERROR: database "database" already exists

What do you expect to happen?

The second db:create should not fail with an error

What is actually happening?

The second db:create is failing with an error : database "database" already exists

A previous issue was intended to address it but was closed: #629
