how to list the files for the next git push command

I am trying to push a branch to origin with

git push --set-upstream origin v0.8

This seems to take forever and eventually stops with an error

  ! [remote rejected] v0.8 -> v0.8 (pre-receive hook declined)
error: failed to push some refs to 'https://github.com/X/X.git'

so apparently it tries to push a file with 1.5Gb named X.sql...? I can't see this file anywhere? So I had a look at the log with

git log v0.8 --not --remotes=origin

which gave

how can I see all files connected to the commit? Just to check with one has the large file? From the answers below I saw that I probably committed a large file and deleted it. In this case git rebase would be the way to remove it. However, rebase does not work if there is no upstream branch? Here is the output for rebase

git rebase -i
There is no tracking information for the current branch.
Please specify which branch you want to rebase against.
See git-rebase(1) for details

    git rebase <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/<branch> v0.8

If I follow this advise I get

git branch --set-upstream-to=origin/v0.8 v0.8
error: the requested upstream branch 'origin/v0.8' does not exist

hint: branch that already exists at the remote, you may need to
hint: run "git fetch" to retrieve it.

my problem could be solved by deleting all current commits and just re-committing and pushing my current version... is that possible?
