This is how you can delete some HUGE dir in your repo's history. Warning! Make a backup and don't try it, if you don't understand what are you doing!
# Let's figure out what we have in the beggning
git fsck --full --strict --unreachable
git count-objects -v
# Filter ALL branches deleteing `db/seeds_assets`
git filter-branch -f --tree-filter 'rm -rf db/seeds_assets' -- --all
# Remove original reflogs
rm -rf .git/refs/original/
