you couldn't use it if that was the case. at a minimum, there is the
postmaster process, the postgres writer, the postgres logger, the
postgres stats collector, and the postgres wal writter. oh, and
autovacuum.. then, each user connection to postgres launches another
instance to service the queries of that connection.
