To speed up, consider to increase vacuum_mem if you have free RAM.

It is safe to kill the vacuum (but not a favored thing to do). I have
done it
many times when the vacuums have run to long and have started to affect
my
online production performance. Be sure to just do a kill, as a kill -9
will
cause the db to reset all connections to it.

Since you have not vacuumed this db in so long, I would probably suggest
vacuuming it table by table so you can have a finer level of control
over the
vacuum.

HTH,

Chris

Hi,

We have a very big db that was not vacuumed for a long time. We started
vacuum 3 days ago and it has not finished yet. There are some urgent
processes that have to be run against the db.

Is it safe to kill vacuum? It was started with 'vacuum full analyze'
Is there anyway to speed it up at next start?

TIA,
