How do you know what the size of the table is? You had at least two
tables you were working on before. I think there must be something
you're not communicating completely. (And why are you worried about
less than 3 Meg anyway? Regular vacuum will leave some empty space
around for new data, which means you don't have to go down to the
filesystem to make the file bigger before you write it it. This is a
Good Thing.)
Please go back and run VACUUM VERBOSE on the table you killed the
vacuum on before.
