The INSERT and COPY paths have been refactored to better handle differences between PostgreSQL versions. In particular, PostgreSQL 12 introduced the new table access mangement (AM) API which ties tuple table slots to specific table AM implementations, requiring more careful management of those data structures. The code tries to adopt the new (PG12) API to the extent possible, providing compatibility layers and functions for older PostgreSQL versions where needed.
