Surely we'd need to know how many _rows_ there are in those tables? Also
how many indexes and index rows?

I believe that PostgreSQL does have greater overhead on disk than MySQL,
however.  Just to have the database started will mean that you have a
number of write-ahead logs (typically 16MB each - on my laptop these
take up 114M) which are used internally by the database server for
transaction handling - MySQL doesn't need these, of course.

Cheers,
                    Andrew.
