As a complete newcomer to WP, I sure would have appreciated that this information be available when I installed WP. I'm going through Hell right now trying to change my 'wp_' prefix. The WP Security Scan is unable to change it automatically (even though I have ALTER privileges), so I'm having to manually edit the SQL backup. I can't figure out how my ISP will let me re-import the data base: there's an Export, no Import. Lotsa fun.

WP should prominently display this info during the installation process.
