Download the installation package: First, you need to download the installation package suitable for your operating system version from the official website (https://www.postgresql.org/download/).
Run the installation program: Execute the downloaded installation program and follow the instructions to install. During the installation process, you can choose the installation location, create a default location for the database, set an administrator password, and other options.
Set up environment variables: After installation, you need to add the path of the bin folder under the installation directory to the system’s environment variables, so that you can use PostgreSQL commands in any path.
To initialize the database: After installation, a new database needs to be initialized. This can be done using the command line tool initdb. For example, you can initialize a new database by typing initdb -D /path/to/data/directory in the command line.
To start the database: after initialization is complete, you can use the command line tool pg_ctl to start the database. For example, enter pg_ctl -D /path/to/data/directory start in the command line to start the database.
To create databases and users: Once the database is initialized, you can use the command line tool createdb to create a new database and createuser to create a new user. For example, typing createdb mydatabase will create a database named mydatabase, and typing createuser myuser will create a user named myuser.
To connect to the database: After installation and configuration, you can connect to the database using the command line tool psql. For example, entering psql -U myuser -d mydatabase allows you to connect with the username myuser to the database named mydatabase.

The above is a basic installation and deployment method. Depending on actual needs and different operating systems, additional configuration and settings may be required. Please refer to official documentation and other resources for more detailed information.
