Обсуждение: effects of cancelling a vacuum full
Hi, I just had to cancel one VACUUM FULL (of a 4.3m row table) that someone ran in business hours. It was after an hour or so that I realized, and it was blocking queries, running out of connections, so I cancelled it. Are there any bad side effects of cancelling an ongoing full vacuum of a table or a database? Does a partial full vacuum give back any space?

Just wait and run it again later. Tell your used to do a vacuum regular during business hours or you'll have to give him a stern talking to.
One Question out of curiosity .. How did u cancel the vacuum full ?.

2. canceled the vacuum full from command prompt eg using "ctrl C".
3. or did an immediate shutdown .
