DEPLOY POSTGRESQL

This was created for diffrent network - so you might see some wired stuff like in the rpms installtion repos.

This deployment is divided to playbooks. We have the master play and the childs that run after. The playbooks flow is this:

• Master play check the reqiured parameters for the other plays
• Child play prerequisite prepere our servers for the cluster and replica deployments
• if pg_type: REPLICA
  • Child play deploy cluster run only on the master.
  • Child play deploy replica run on the servers.
• else
  • Child play deploy cluster run on all given hosts.
