For a start I guess it begs to be asked if the users who has
postgresql-common package installed are likely to ever use the
pg_createcluster script at all... based on that alone a Depends might
not be warranted.

Looking at the code we'll find the following use of chattr:

    # disable copy-on-write semantics for PostgreSQL data on btrfs and similar;
    # this fails on file systems which don't support it, so ignore errors
    system "chattr +C '$datadir' 2>/dev/null";

This doesn't make me feel a dependency is warranted. Possibly a Recommends
or Suggests. Even just closing this bug report with no action could seem
like the proper response to me.

Would be great to hear maintainers view on this.
