It is always best to show the full version number, just in case one of
the bugs fixed in a minor release could matter for the issue at hand.
(In this case I don't know of any, but there is not much point
checking for sure when I can only guess at what you are running.)

Again, copy/paste of what you saw would allow a response with higher confidence.

Not if it processed the Ctrl+C before the command completed normally.
Either all rows in the table should be gone or the DELETE had no
effect.
Note that now would be a horrible time to suffer database corruption.
If, for example, you needed to run pg_resetxlog right now, you might
lose a lot of those rows. Tread carefully.
