I did a brief review of v39-0001 and v39-0002.
text:
COPY_FILE
COPY_FRONTEND
still appear on comments in copyfrom_internal.h and copyto.c,
Should it be removed?
+#include "commands/copyto_internal.h"
#include "commands/progress.h"
#include "executor/execdesc.h"
#include "executor/executor.h"
#include "executor/tuptable.h"
"copyto_internal.h" already include:
#include "executor/execdesc.h"
#include "executor/tuptable.h"
so you should removed
"
#include "executor/execdesc.h"
#include "executor/tuptable.h"
"
in copyto.c.
CREATE FUNCTION test_copy_format(internal)
RETURNS copy_handler
AS 'MODULE_PATHNAME', 'test_copy_format'
LANGUAGE C;
src/backend/commands/copy.c: ProcessCopyOptions
if (strcmp(fmt, "text") == 0)
/* default format */ ;
else if (strcmp(fmt, "csv") == 0)
opts_out->csv_mode = true;
else if (strcmp(fmt, "binary") == 0)
opts_out->binary = true;
else
{
List *qualified_format;
....
}
what if our customized format name is one of "csv", "binary", "text",
then that ELSE branch will never be reached.
then our customized format is being shadowed?

"The extra parentheses were required before PostgreSQL version 12, but
are now optional."
means that
ereport(NOTICE, (errmsg("CopyFromInFunc: attribute: %s",
format_type_be(atttypid))));
can change to
ereport(NOTICE, errmsg("CopyFromInFunc: attribute: %s",
format_type_be(atttypid)));
all
ereport(ERROR, (errcode(ERRCODE_INVALID_PARAMETER_VALUE), ....
can also be simplified to
ereport(ERROR, errcode(ERRCODE_INVALID_PARAMETER_VALUE), ....
