Yes, that's good!
I had a quick look again, and about the comment:
/*
* If partitioning is not enabled and server version is 14.0 or later, we
* can take account of freeze option of copy.
*/
I'd suggest instead the shorter:
/* use COPY with FREEZE on v14 and later without partioning */
Or maybe even to fully drop the comment, because the code is clear enough
and the doc already says it.
