Hi all, For most beginners (and even a lot of advanced users) there is a strong confusion between simple VACUUM and VACUUM FULL. They think "full" is simply an option to the maintenance operation vacuum while it's not. It's a complete different operation.
I have a hard time explaining it when I teach PostgreSQL Administration (even if I stress the matter) and I constantly meet customer that are wrong about it. I think that the way we name this two operations is not helping them. I had to work with SQL Server some years ago and they use the word "SHRINK" to do something similar to "VACUUM FULL". I don't know if it's the best option, I think others can be found (COMPACT, DEFRAGMENT...) Of course, for compatibility reasons, VACUUM FULL should always be available, but I think an alias that is less confusing for people could be a good thing. What do you think ? Cheers, Lætitia
