Can someonw clarify whether the DB will grow forever , if we never do
a vacuum (either with these commands or via the engine-upgrade)?
The postgres database runs autovacuum regularly by default and engine
defines some vacuum variables in postgresql.conf to be more efficient.
Autovacuum runs standard vacuum (not FULL) and this can reclaim less space.
When you have smaller environment the grow of dwh database is not to
significant but with big setup it can be different. So is good to run
full vacuum in some time to reclaim more space. The thing is that this
takes a lot of time and tables are locked, so engine/dwh can't work with
them properly and need to be stopped.
