Here is a new submission with the expected "context diff format".
> Dear PostgreSQL developers,
>
> Plese find attached a patch so that:
>
> Make "psql -1 < file.sql" work as with "-f"
>
> Make psql --single-transaction option work on a non-interactive
> standard input as well, so that "psql -1 < input.sql" behaves as
> "psql -1 -f input.sql".
>
> This saner/less error-prone behavior was discussed in this thread back in
> June:
>
> http://archives.postgresql.org/pgsql-hackers/2012-06/msg00785.php
>
> I have tested it manually and it works for me. I'm not sure this is the best
> possible implementation, but it is a small diff one. I haven't found a place
> in the regression tests where "psql" could be tested with different options.
> Did I miss something?
