-    LOG_S3_BUCKET: path to the S3 bucket used for PostgreSQL daily log files (i.e. foobar, without s3:// prefix). Spilo will add /spilo/{LOG_BUCKET_SCOPE_PREFIX}{SCOPE}{LOG_BUCKET_SCOPE_SUFFIX}/log/ to that path. Logs are shipped if this variable is set.

In order to avoid (unlikely) issues with restoring WALs (from S3/GC/and so on) when switching to spilo-13 please set the ENABLE_WAL_PATH_COMPAT=true when deploying old cluster with spilo-13 for the first time. After that the environment variable could be removed. Change of the WAL path also mean that backups stored in the old location will not be cleaned up automatically.
