PostgreSQL 9.5.2
Thanks.
This was the input/output on the screen:
username=# delete from some_table;
^CCancel request sent
ERROR: canceling statement due to user request
This was the output in the PostgreSQL log:
user::2016-05-19 13:37:16 CDT STATEMENT: delete from some_table;
user::2016-05-19 13:40:38 CDT ERROR: canceling statement due to user request
user::2016-05-19 13:40:38 CDT CONTEXT: while deleting tuple (54598,61) in relation "some_table"
Thanks again!
Lance

It is always best to show the full version number, just in case one of the bugs fixed in a minor release could matter
forthe 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.
