Instead of copying over a mostly-unchanged `postgresql.conf`, we transition to deploying a `conf.d/zulip.conf` which contains the only material changes we made to the file, which were previously appended to the end. While shipping separate while `postgresql.conf` files for each supported version is useful if there is large variety in supported options between versions, there is not no such variation at current, and the burden of overriding the entire default configuration is that it must be keep up to date wit the package's version.
