May I know which patch you are referring to? And, what do you mean by

Please help me understand the meaning here.

So, do you mean to prohibit ON_ERROR being specified without any value
like in COPY t1 FROM stdin WITH (ON_ERROR);? If yes, I think all the
other options do allow that [1].

Even if we were to do something like this, shall we discuss this separately?

Having said that, what do you think of the v13 patch posted upthread?

[1]
postgres=# COPY t1 FROM stdin WITH (
DEFAULT ESCAPE FORCE_QUOTE HEADER QUOTE
DELIMITER FORCE_NOT_NULL FORMAT NULL
ENCODING FORCE_NULL FREEZE ON_ERROR

postgres=# COPY t1 FROM stdin WITH ( QUOTE );
ERROR: relation "t1" does not exist
postgres=# COPY t1 FROM stdin WITH ( DEFAULT );
ERROR: relation "t1" does not exist
postgres=# COPY t1 FROM stdin WITH ( ENCODING );
ERROR: relation "t1" does not exist
