Honestly, I'd love to see something like "--script" that does a number
of things:

Forcibly set (regardless of .psqlrc, in particular):
--no-psqlrc
--echo-all
--single-transaction

ON_ERROR_ROLLBACK=off
ON_ERROR_STOP=on
AUTOCOMMIT=off

Assume "-f -" if no -f passed in (provided this actually works as
expected.. I'm not sure it does, I remember there being some discussion
about this recently).

Thanks,

Stephen
