 * The VIEW created by prometheus-exporter can cause pg_upgrade to fail. If this occurs you should remove `postgres_exporter.pg_stat_activity` and re-install post upgrade with `/usr/local/bin/docker-initdb-run /docker-entrypoint-initdb.d/prometheus-exporter.sh`.
 * Postgres images 9.6-dev and 12 have `POSTGRES_INITDB_ARGS="--data-checksum"` by default which will conflict if the source was not using data checksum. You can set `POSTGRES_INITDB_ARGS=""` to avoid the issue during upgrade.
 * The `9.6-to-12-upgrade` image does NOT support timescaledb upgrade.
