Question 1Which tool can you use to both design and create a Postgres database?1 pointQuery ToolERD Tool pgAdminpsql

You can use both pgAdmin and psql to design and create a Postgres database.

pgAdmin is a web-based interface for managing PostgreSQL databases. It provides a visual, user-friendly environment with a host of practical solutions that make managing databases easy. With pgAdmin, you can create, manage and use databases in a straightforward manner, execute SQL queries, manage data and implement many other features.

psql is a terminal-based front-end to PostgreSQL. It enables you to type in queries interactively, issue them to PostgreSQL, and see the query results. Alternatively, input can be from a file or from command line arguments. In addition, it provides a number of meta-commands and various shell-like features to facilitate writing scripts and automating a wide variety of tasks.

However, if you are specifically looking for a tool that can help you in designing the database i.e., creating ER diagrams etc, then ERD Tool would be more appropriate. But please note that ERD Tool is not specifically tied to Postgres and it does not create a database, it is used for designing and modeling a database.
