That will be determined by the columns you define and the data you insert.

Read http://www.postgresql.org/docs/8.2/interactive/storage-toast.html
to get an explanation of TOAST and how you can change the settings if
you wish.


This is most likely the reason for your "lack of compression" - the data
in the toast tables is most likely already compressed data so will be
close to a 1-1 export size.
