How to Drop Multiple Databases in PostgreSQL

Introduction While performing database integration tests, things went south, and I ended up with more than 15 (fifteen) temporary PostgreSQL test databases. I use OmniDB, an open-source application for managing databases. Version (3.0.2b) of OmniDB does not have an option for selecting and dropping multiple databases. To drop a database in OmniDB, you right-click on a database, select Drop Database from the context menu, run the query to drop the database, and finally close the query window.
