pg_log 100MB per day !!! on 5MB of data

PLEASE does anybody know any sopution how to avoid patholigical grought of
pg_log in 6.5.1.
I am intensively using begin transactin - end transaction and every 15
minutes regenerating some tables inside transaction block.
But 1 GB of bloat in 10 days is unacceptable.

Thank for ANY response.

Are you considering it as a bug or is this only feature?

Is there any chance when I downgrade to 6.4. that the behaviour changes?
