[TYPO3] Database size requirements

[Lukas Mattsson]

What is the minimum recommended database size to run Typo3?
I am building a typo3 site for a customer, but he has only 2 mb space on 
  his web hotel for mysql. My fresh installation with a few pages, 
phpmyadmin and templavoila use 6.0 MB database after clearing FE cache. 
Is it possible to reduce the db requirement that far or do he need to 
switch to a better web hotel?
