Ctrl-C, AFAIK, sends the INT(errupt) signal in *ix, which normally
stops looping things. That's the standard way to interrupt long
running commands, send them the interrupt signal.

I haven't read the relevant sources, but my bet is psql is catching
int in *ix to do that ( it does it for other things ).

IIRC windows does similar stuff, although I think Ctrl-break had to be
used, but I haven't used it since the dawn of the century.

That ( knowing how to interrput things ) is not a programming, but a
basic OS - user issue.
