This was a testing oversight that came from #61009 -- I forgot to test
the new traceFormat option with older server versions while I was
working on FDB 6.1.
Since trace_format is only available in 6.1+, emitting it
unconditionally caused older versions of the database fail to start,
reporting an error. We simply gate it behind a version check instead,
and assert the format is always XML on older versions. This avoids the
case where the user has an old version, changes traceFormat willingly,
and then is confused by why it didn't work.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-19.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-19.03
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
