drop_database

DROP 
DATABASE(7)					  PostgreSQL 9.2.7 Documentation					  DROP DATABASE(7)

NAME

       DROP_DATABASE - remove a database

SYNOPSIS

       DROP DATABASE [ IF EXISTS ] name

DESCRIPTION

       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. Also, it cannot be executed while you or anyone else are connected to the target database. (Connect to
       postgres or any other database to issue this command.)

       DROP DATABASE cannot be undone. Use it with care!

PARAMETERS

       IF EXISTS
	   Do not throw an error if the database does not exist. A notice is issued in this case.

       name
	   The name of the database to remove.

NOTES

       DROP DATABASE cannot be executed inside a transaction block.

       This command cannot be executed while connected to the target database. Thus, it might be more convenient to use the program dropdb(1)
       instead, which is a wrapper around this command.

COMPATIBILITY

       There is no DROP DATABASE statement in the SQL standard.

       CREATE DATABASE (CREATE_DATABASE(7))
