Code review comment for lp:~roadmr/canonical-identity-provider/wrong-location-psql-config

I think it's meant to overwrite it, particularly since the default config file is mostly all commented out and has default values.

This is used for development only and I checked that all the tests pass (OTOH it wasn't any faster with the custom settings, beh). So it works but I'm happy to rescind this if you think it's weird (or maybe modify it so it does what you said and append to the existing file rather than clobbering it). No rush, let me know what you'd prefer :)
