For ^C it may have been a side-effect of the SIGINT changes, though I
doubt it. One of the first things psql does is setup a ^C handler and
it only ever did a siglongjmp in that case. But there was no setjmp
done at that point, so a ^C would have been a no-op.

psql uses simple_prompt which I beleive comes from the port directory.
And there is definitly a loop there to retry on no input. That hasn't
changed any time recently as far as I can tell.

Have a nice day,
