How far does interrupting vacuum full rollback?

Dear Folks,

I would like to interrupt this full vacuum run as:

vacuum full verbose;

which has vacuumed a number of tables.

Will interrupting it (with Control-C) cause vacuuming of the previous
tables to be rolled back, or just the vacuuming of the current table?

WIll any of the work done on the current table remain if the vacuuming
process is interrupted?

This is PostgreSQL 7.3.8.
