When upgrading to any version of JDBC driver starting with 42.3.0 my performance tests that are heavy on inserting records (and lots of blobs by the way) show 2x slow down. I couldn't find anything suspicious in the changelog, so if anyone can give me the directions on how to research/troubleshoot this problem, I'd greatly appreciate it.

PostgreSQL version: 13.2
Operating system:   Ubuntu
