Config files are global, so I doubt it.
if it's a web app with persistent connections, then splitting onto several databases may consume more RAM. Example: 100 apache clients connected to 3 databases creates 300 forked postmaster processes ; vs 100 apache clients connected to the same DB using three schemas only takes 100 postmasters
