Review comment:
Yes, usually it should.
My intention for this example is to make this example "runnable out of box";
That says if user copy-paste the example to its IDE, and has postgres installed
with default set up, it would work.
I installed postgre and `postgres` is the default table can be accessed
without username and password or default (username and password).
