B) VACUUM ANALYZE - the one that cleans up and updates the stats. Perfect for keeping my database running smooth like a well-oiled machine!

NOTIFY? I'll just send a carrier pigeon to let the database know it's time for a cleanup.

EXPLAIN ANALYZE? I prefer to just 'explain' to my boss why the database is slow.

I'm not sure, but I think it might be B) VACUUM ANALYZE because it also updates statistics.

I agree with Thomasena, VACUUM is used to reclaim space and update statistics.
