Requirements
------------
* **On master node :** Slaves must be able to connect with user from `recovery.conf` to database with the same name (or another specify with `-D`) as trust (or via md5 using password specify in `~/.pgpass`).
* Some CLI tools: `sudo`, `awk`, `sed`, `bc`, `psql` and `pg_lscluster`
* **On standby node :** `PG_USER` must be able to connect localy on the database with the same name (or another specify with `-D`) as trust (or via md5 using password specify in `~/.pgpass`).
* **On master node:** Slaves must be able to connect with user from `recovery.conf` (or user specify using `-U`) to database with the same name (or another specified with `-D`) as `trust` (or via `md5` using password specified in `~/.pgpass`). This user must have `SUPERUSER` privilege (need to get replication details).
* `sudo` must be install on each nodes.
* **On standby node:** `PG_USER` must be able to connect localy on the database with the same name `(or another specified with -D)` as `trust` (or via `md5` using password specified in `~/.pgpass`).

port if detected or use 5432)
-D dbname Specify DB name on Postgres master/slave to connect on (Default: PG_USER, must
