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?

Thanks,
Anjan
