Terraform plan ran successfully. One note is that the DB parameters will be applied before the RDS instance re-sizing takes place. However, since we're tuning the parameters down, not up, it shouldn't impact current job runs (i.e. DB shouldn't run out of resources due to parameter over-provisioning).
