Hi all, I'm running 11.5 and I'm monitoring pg_stat_progress_vacuum every 2 seconds, while doing from another connection per-table VACUUMs. Every vacuum last 30 or more seconds, so I was expecting to see a record within pg_stat_progress_vacuum, but nothing appears if the vacuum is full. I suspect this is due to vacuum full performing a side-by-side table rewriting, rather than in-place actions against the original table, but I'm not sure if this is real reason or if I'm missing something.
If you're executing VACUUM FULL, you should be looking at pg_stat_progress_cluster:
