pg_dump and database size question

[Birta Levente <blevi.linux@xxxxxxxxx>]

Hi,


I have postgres 9.0.2  server with a 2.4GB database.
After pg_dump of the database, the size increased with aprox 200MB ... why?
I make some tests and the total_relation_size is increased, but the 
relation_size not.

thanks

Birta Levente
