For example you can listen on 0.0.0.0 but provide service on some

running behind firewall, load balancer or inside for example docker.

Hardened the health checks and implemented a real status page.
...
For the postgresql helper, hardened the code to get "the" cursor of the postgresql instance.
For the statuspage, a small status json is returned.
To find out what status a PostgreSQL cluster is in we use the cursor (instead of the provided query() function), as the query function does some retrying etc. For the healthcheck we want to simple provide an answer to a simple query, if we have to reconnect, we are not *that* healthy anyway.
Dropped catching exceptions in the do_GET block, as the HTTPServer will do that nicely for us anyway.
