# This script is designed to run as an init script in a postgres docker container.
# The docker-entrypoint.sh script does not traverse a nested directory
# structue to load sql files at container start. However, it does allow for
# running .sh files. This script should run first to execute the boundary sql
# migration files in the correct order.
