Enabling the trace mechanism by creating a file is no longer supported. The MySQL compatibility extension fromUnixTime now uses the English locale. Some database metadata operations did not work for non-admin users. When using LOG=2, the index file grew quickly in some situations.

DATABASE(7) SQL Commands 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 [dropdb(1)] instead, which is a wrapper around this command. COMPATIBILITY
There is no DROP DATABASE statement in the SQL standard. SEE ALSO
