"traditional" replication - selected databases ?

[lejeczek <peljasz@xxxxxxxxxxx>]

    hi guys,
      
      I've set up replication perhaps only a several times - and only
      now when I wondered I failed to sroogle a clear answer to - is
      possible that way to replicate only selected databases?
      By "that way" I mean - nothing fixed in-between, no third-parties,
      pure pgSQL to pgsql.
      Will it be purely & only by means of _pg_hba.conf_ (surely
      no..) ?
      
      many thanks, L.
