The PostgreSQL trash can is a PostgreSQL plugin that implements a trash can/wastebasket/rubbish bin/recycling container. You drop a table and it's not really gone but only moved to the trash. This allows desktop-minded users to drop tables willy-nilly while giving them the warm and fuzzy feeling of knowing that their data is still there (while giving administrators the cold and, uh, unfuzzy feeling of knowing that disk space will never really be freed again). Now they only need to think of "vacuum" as "disk defragmentation", and they'll feel right at home.
