Lists all running non-replica Cloud SQL instance names

# XXX: only running instances can do exports, otherwise will error out
# XXX: only non-replicas back up correctly due to conflicts with ongoing replication recovery operations - see description above for details
# gcloud sql instances list --format='get(name)' --filter 'STATUS=runnable' | grep -v -- '-replica$'
# better to not rely on the name having a '-replica' suffix and instead use the JSON instanceType field to exclude replicas
gcloud sql instances list --format=json | jq -r '.[] | select(.instanceType != "READ_REPLICA_INSTANCE") | select(.state == "RUNNABLE") | .name'
