pg_lsclusters specifically looks for clusters managed by the pg_createcluster tool

pg_lsclusters searches the directories under /etc/postgresql to find the configuration of the clusters

pg_createcluster (and pg_lscluster, pg_ctlcluster) are Ubuntu/Debian-specific wrappers around initdb and pg_ctl precisely for the purpose of providing a simpler interface for managing multiple postgresql instances on the same host.
