Forgot to add to previous post. As you are changing the major version
you should go the Release Notes section for each major version(15-18)
and read through the notes for the changes that may affect you. It is
generally sufficient to look at just the initial release for each major
version as that where the new/breaking features are called out. Ideally
you would set up a test instance and verify that your code works in the
Postgres major version you wish to migrate to.
