No such command exists. For starters, no command in SQL can do stuff in
other databases than the one you are connected to.
You can write a simple one-liner that will do it, in your shell.
shouldn't be really complex - get list of dbs, and in each db connect
with psql and truncate all tables. basically: `psql | xargs psql`
