Few comments
1) I understood the problem, your first approach is ok for me.
2) Here in error we say column c1 violates not-null constraint and in
the context we show column c2, should the context also display c2
column:
postgres=# create table t3(c1 int not null, c2 int, check (c1 > 10));
CREATE TABLE
postgres=# COPY t3 FROM STDIN WITH (on_error set_to_null);
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself, or an EOF signal.
>> a b
>> \.
ERROR: null value in column "c1" of relation "t3" violates not-null constraint
DETAIL: Failing row contains (null, null).
CONTEXT: COPY t3, line 1, column c2: "b"
3) typo becomen should be become:
null will becomen reserved to non-reserved
4) There is a whitespace error while applying patch
Applying: COPY (on_error set_to_null)
.git/rebase-apply/patch:39: trailing whitespace.
a <literal>NOTICE</literal> message indicating the number of rows
warning: 1 line adds whitespace errors.
