This message is returned if the command is 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.
DROP DATABASE removes the catalog entries for an existing database and deletes the directory containing the data. It can only be executed by the database owner (usually the user that created it).
DROP DATABASE cannot be undone. Use it with care!
