Source represents a configuration how to get databases to monitor. It can be a single database, a group of databases in postgres cluster, a group of databases in HA patroni cluster.
MonitoredDatabase represents a single database to monitor. Unlike source, it means a single physical database connection. Continuous discovery sources (postgres-continuous-discovery, patroni-continuous-discovery, patroni-namespace-discovery) will produce multiple monitored databases.
pgwatch first reads sources (single dbs, postgres and patroni clusters) and then lists all found databases in those as monitored databases
