Ah! Yeah, I knew that and forgot :-) It's easier than that actually --
you just need to keep the pipe open in another process. So I can do
this: first open a terminal with
$ psql -f foo
And then, in another terminal,
$ cat > foo &
[1] 29155
[1]+ Stopped cat >foo
$ echo "begin;" > foo
$ echo "create table a (a int);" > foo
$ echo "insert into a values (1);" > foo
$ echo "insert into a values (2);" > foo
$ echo "insert into a values (3);" > foo
$ echo "commit;" > foo
$ echo "select * from a;" > foo
$ kill %1
-bash: echo: write error: Appel système interrompu
[1]+ Complété cat >foo
And while this is going on, the other terminal shows the output being
produced by psql.
Thanks for the reminder :-)
