Database setup

I got the following error while database setup!

I am not able to edit the pg_hba.conf , when I try to open the file in my editor , it shows a blank file
how to edit that?

I am already using BOOKBRAINZ database, how to manage MUSICBRAINZ database at the same time,?.
I mean do setup of one database affect other?.

Please help

Since you already have a running database, connect to it and run:

SHOW hba_file;

It should show you the path to the relevant file. If that file doesn’t exist, create it.

do setup of one database affect other?

Possibly, but I don’t know of any incompatibility between BookBrainz and MusicBrainz here.


Thanku @yvanzo
