No. It is often safe to just do git-push, unless you have naive
developers doing pull every time some ref in your shared repo changes
*and* expecting the result to compile (typical for CVS way of work).
git-push will not overwrite anything, it always only forwards history.

For the case you really want to know what the changes on remote repo
will be it is possible to fetch them into the local repo first and
compare with what you will push:

    $ git fetch git://remote/path/REPO master:refs/remotes/REPO/master
    $ gitk local..REPO/master

It gives you all possible information, which may be worth that bit of
work. Or, if you have all the remote configuration ready, it can be
just:

    $ git fetch
    $ gitk local..REPO/master
