If you want to analyze a VACUUM log, just run vacuumdb with the option
you need (for example -a -z -v -f for a vacuum full analyze verbose).

# vacuumdb -a -z -v -f > your_log_file.log

Then analyze this log file as explained on the pgFouine website.

This is completely different and it's useful for query log analysis.
So you don't care if you just want to analyze your vacuum behaviour.
