OS Centos 6 running on a VM

I have a large table (over 100Gb including indexes) 

The machine is slow

I have issued and alter column against the following;

 price_id         | integer                     | not null default nextval('bet.price_price_id_seq'::regclass) | plain   |              |

As;

ALTER TABLE bet.price ALTER COLUMN price_id TYPE bigint;

The process has taken a very long time, I know that it is rebuilding the table and a lot of temp files have been created, deleted etc

It now seems to have gone quiet (no temp disk files etc), it still seems to be clicking up CPU

- Is there a final part of the process where it may just be doing validation etc?

- Is it safe to terminate the process?

Many thanks
