DROP DATABASE
DROP DATABASE — remove a database
Synopsis
DROP DATABASE [ IF EXISTS ] name [ [ WITH ] ( option [, ...] ) ]
where option can be:
FORCE
Description
DROP DATABASE removes 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. It cannot be executed while you are connected to the target database. Also, it cannot be executed if anyone else is connected to the target database, unless you use the FORCE option described below.
DROP DATABASE cannot be undone. Use it with caution!
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 be removed.
FORCE
Attempt to terminate all existing connections to the target database. It does not terminate if prepared transactions, active logical replication slots, or subscriptions exist in the target database.
This will fail if the current user does not have permission to terminate other connections. The required permissions are the same as those described for pg_terminate_backend. This will also fail if we cannot terminate connections.
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 instead, which is a wrapper for this command.
