RE: Question on postgresql.conf

Hi.

As far as I know, it's not currently possible. Maybe recompiling, but that could not be the best for production environment. I suppose this is this way becuase postgres is designed to expect a certain folder structure for it's data folder, and configuration files are considered part of it.

As you may see on the documentation:

https://www.postgresql.org/docs/9.6/static/app-postgres.html

You can change the data folder (-D command line option), but, no matter what the data folder is, it MUST have a postgresql.conf, as well as pg_hba.conf

However, some distros have made a similar appriach to what you may be looking to do. Don't remmeber which one, but there's a distro which it's stabdard postgresql server packages store configuration files at /etc/postgresql, while storing data at /var/lib/postgresql. This is done by simoly making a symlink, like "ln -s /mnt/shared/postgres/server1.conf /var/lib/postgres/data/postgresql.conf". Same applies to other conficuration files.

Also, if I'm not wrong, you can set custom permissions on configuration files(ONLY configuration files, the rest of the data folder must preserve postgres standard permissions). Just make sure the postgres user(or the user you will be using to run postgres) can read the configuration files.
