That's exactly the point. Use the one that scales to your requirements. 
Each was designed to address needs, at orders of magnitude different from 
each other. However there is a tendency for application developers to scale 
up or scale down their applications to tap wider markets. (Am not sure how 
good or how bad such a trend is). However,  I would not want to use Oracle 
in small-scale database environments. At the same time I would not as 
yet  recommend MySQL for  large database systems.

There may be some difficulty in defining how  small is "small" and how 
large is "large". There would also be many other considerations like kind 
of information being stored in the database,  complexity of the relations 
between tables etc..etc.... which goes into decisions on what to use when. 
It's useful to hear experiences of people who have used Mysql,Postgre, 
Oracle etc... in different environments.
