This is similar to Andreas' solution, and which we use in our shell scripts:
postgres@arya ~]$ psql mydb -c "SELECT cola, colb, description FROM

If the sql string contains multiple commands, they will be executed
within a single transaction, unless you use BEGIN/COMMIT within it to
split it up into multiple transactions.
