Hi,

Unless you do isatty(STDIN_FILENO). Nothing should change for
noninteractive mode. However, I agree that it might be annoying.

If you just output a rollback command on exit, then it is already too
late to rescue the pending transaction, so I'm not sure whether that
would help this use case so much.

What do you think about displaying a different prompt when a
transaction is pending, like showing the number of open transactions
in parentheses or so? '(2 transactions pending) mydb$' is way too
long, and '(T2) mydb$' is not intuitive. Hmm..

Thanks,

Martin
