It turns out that PostgreSQL comes with weird default that allows passwordless authentication for localhost connections [1]. This essentially means that 'password' input parameter for this action was ignored.
The 'setup-postgres' action's primary use case is to be used on CI where most of the time authentication is desired in order to verify that passwords are passed correctly from applications under test.
This patch enforces password authentication even for localhost connections, making sure that passwords are verified and not ignored. This will break everyone who previously passed wrong password or didn't pass it at all.
