postgres PWD as parameter

Goal

If auth is set to MD5, and ssh connection to remote server is available, the script asks for the DB user's password several times, and in one step it asks several times at once without waiting for user input and failing to run the tests, so the final report is almost empty. Even without this error is quite unfriendly to ask for the password one or more times per test.

No problem at all if auth is set to peer (obviuously)

TODO / How to implement

Add Postgres password parameter support to the cli
