DROP 
DATABASE(7) SQL Commands DROP DATABASE(7) NAME
DROP DATABASE - remove a database SYNOPSIS
DROP DATABASE name INPUTS name The name of an existing database to remove. OUTPUTS DROP DATABASE This message is returned if the command is successful. DROP DATABASE: cannot be executed on the currently open database 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. DROP DATABASE: may not be called in a transaction block You must finish the transaction in progress before you can call this command. DESCRIPTION
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! NOTES This command cannot be executed while connected to the target database. Thus, it might be more convenient to use the shell script dropdb [dropdb(1)], which is a wrapper around this command, instead. Refer to CREATE DATABASE [create_database(7)] for information on how to create a database. COMPATIBILITY
SQL92 DROP DATABASE statement is a PostgreSQL language extension; there is no such command in SQL92. SQL - Language Statements 2002-11-22 DROP DATABASE(7)
