Is there a quick way(other than vacuum full) to re-init the transaction
ids. (I can afford some downtime)

The shutdown/restart was a waste of typing, and -f doesn't really help
here either.

I'll bet a nickel you did not run the vacuum as superuser. It has to be
done by a superuser to have permission to vacuum every table in the
database (including system catalogs).
