VACUUM FULL

Read the docs to understand what it does. Deleting a row does not shrink the table. 

Think about it, what happens when you delete a row that's first in the file on disk? Do you expect the rest of the table to be rewritten? Do you expect the file to be rewritten every time a row is deleted? On commit of any transaction that included a delete?

Postgres will eventually reuse the space left behind by deleted rows (read the docs for VACUUM), so under most use cases this is not a problem.
