A quick explanation of how to switch between databases inside the `psql` tool in PostgreSQL
Inside psql, you always have one active database, where you are “into”. By default it’s the one you connect to in the first place. When you run:
psql postgresyou’ll connect to the postgres database.
To switch database, use the \connect command, or \c:
PostgreSQL will close the connection to the previous database you were connected to, and will connect to the new one you specified.
