after, i think.
test=# create table foo (id int primary key, name text);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "foo_pkey" for table "foo"
CREATE TABLE
test=*# copy foo from stdin;
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
>> 1 a
>> 2 b
>> 2 c
>> \.
ERROR: duplicate key violates unique constraint "foo_pkey"
CONTEXT: COPY foo, line 3: "2 c"
test=*#
I can type the wrong key and the error occurs later with the finaly \.
