Okay,

updating some tables once a day isn't actually replication.

For this to happen, I would suggest you connect the two machines by
using the Foreign Data Wrapper and then:

  * set up a foreign table
  * create a materialized view on the "slave" as "select * from
    foreign_table"
  * set up a job for refreshing the materialized view

Regards,

Holger
