Please, don't top post. Reply in-line.
You have not reported if you tried upgrading to 12.20. Chances are this
issue was already fixed since 12.16, people are unlikely to spend time
investigating this, only to find it was a waste of time.
Also, Tom asked you a couple important questions you ignored:

Please provide this info. It was suggested to try with "jit=off", so
maybe try that too - I personally don't see why would that matter for
the COPY command, but maybe it does ...
Finally, I wonder if you're simply misinterpreting what RES means. It's
not "private memory used by the process". So if you're simply seeing RES
to grow to 10GB and conclude "memory leak", it may not be the case. It
could be shared memory, for example - you need to inspect "smaps" for
the process to see what exactly the RES figure includes.
