DROP DATABASE drops a database. It removes the catalog entries for the database and deletes the directory containing the data. It can only be executed by the database owner.
DROP DATABASE cannot be undone. Use it with care!
This message is returned if the command was successful.
You cannot be connected to the database you are about to remove. Instead, connect to template1 or any other database and run this command again.
You must finish the transaction in progress before you can call this command.
This command cannot be executed while connected to the target database. Thus, it might be more convenient to use the program dropdb instead, which is a wrapper around this command.
