To start a new Docker container using the official PostgreSQL image, follow these steps:

1. Pull the PostgreSQL Docker Image: First, ensure you have the latest PostgreSQL image by pulling it from Docker Hub. Use the following command:

    docker pull postgres
   

2. Run the Docker Container: Start a new container with the name "postgres-sql-series" and set the environment variable POSTGRES_PASSWORD to "postgres". Run the container in detached mode using the -d flag:

    docker run --name postgres-sql-series -e POSTGRES_PASSWORD=postgres -d postgres
   

3. Access the PostgreSQL Database: To access the PostgreSQL database within the container, you can use the docker exec command to open a psql shell. Here’s how you can do it:

    docker exec -it postgres-sql-series psql -U postgres
   

4. Create a New Database: Once inside the psql shell, you can create a new database using the SQL command:

    CREATE DATABASE your_database_name;
