Comment:

 [attachment:35560.diff] doesn't work as expected in my testing:
 1. By the time `setup-config.php` checks the connection, `require_wp_db()`
 is already run via `wp-settings.php`.
 2. If the values are already defined on first run, this prevents `setup-
 config.php` from [https://core.trac.wordpress.org/browser/tags/4.9.4/src
 /wp-admin/setup-config.php?marks=264-276#L264 redefining them] to test the
 connection with user-supplied values.

 [attachment:35560.2.diff] is an alternative approach.
