v0.68.2

• Allow explicitly setting Cluster ID
  • The new api_cluster_id / API_CLUSTER_ID setting enables overriding the
    automatically detected cluster ID, or set it on platforms that don't have
    built-in detection.
  • This value is stored by pganalyze for each server, and used for grouping
    servers together. Alternate mechanisms to create server groups in pganalyze
    will be offered in a future release.
