I don't think that's equivalent. An Oracle instance is a runtime concept
(the collection of server processes on a single machine serving a single
database (the collection of files on the disk)) whereas a PostgreSQL cluster is
both a data and a runtime concept (config + data files for several
databases with some shared data + the processes serving them). Also
instance:database is n:1 while cluster to database is 1:n. Very
different.
