## Description

Custom backfill script for populating `tx_affected_objects` by loading
the raw effects from the database and pulling the `object_changes` from
it.

Includes a small clean-up parameterising the script-based SQL backfills.

## Test plan

Ran an updated version of this script locally, just printing the values
to be added and ran that locally.

your changes, release notes aren't required.

For each box you select, include information after the relevant heading
that describes the impact of your changes that a user might notice and
any actions they must take to implement updates.
