Thanks for your reviewing and comments!
I noticed that you used _ignore_datatype_errors_specified_ variable in
_copy.c_ , but guc has a short name _ignore_datatype_errors_. Also you
used the short variable name in _CopyFormatOptions_ structure.
You may already understand it, but these variable names are given in
imitation of FREEZE and BINARY cases:

Name used _ignore_datatype_errors_specified _is seemed very long to
me, may be use a short version of it (_ignore_datatype_errors_) in
_copy.c_ too?
I think it would be sane to align the names with the FREEZE and BINARY
options.
I agree with the name is too long and we once used the name
'ignore_errors'.
However, current implementation does not ignore all errors but just data
type error, so I renamed it.
There may be a better name, but I haven't come up with one.
Besides, I noticed that you used _ignored_errors_ variable in
_CopyFromStateData_ structure and it's name is strikingly similar to
name (_ignore_datatype_error__s_), but they have different meanings.
Maybe it will be better to rename it as _ignored_errors_counter_?
As far as I take a quick look at on PostgreSQL source code, there're few
variable name with "_counter". It seems to be used for function names.
Something like "ignored_errors_count" might be better.
