Hello, I've read the docs at [1] and also this interesting recent post about adding binary I/O to the hashtypes extension. I wrote send & recv functions for my new multirange types, but I'm not sure how to test them. After running installcheck or installcheck-world, the code coverage report says they aren't tested, nor are the send/recv functions for ranges or arrays. When does Postgres actually use these functions? Is there a good way to test them? Thanks, Paul [1] https://www.postgresql.org/docs/11/xtypes.html [2] http://www.myrkraverk.com/blog/2019/08/postgresql-retroactively-adding-binary-i-o-to-a-type/
