"use database_name" command in PostgreSQL

I am beginner to PostgreSQL.

I want to connect to another database from the query editor of Postgres - like the USE command of MySQL or MS SQL Server.

I found \c databasename by searching the Internet, but its runs only on psql. When I try it from the PostgreSQL query editor I get a syntax error.

I have to change the database by pgscripting. Does anyone know how to do it?

When you get a connection to PostgreSQL it is always to a particular database. To access a different database, you must get a new connection.

Using \c in psql closes the old connection and acquires a new one, using the specified database and/or credentials. You get a whole new back-end process and everything.
