Yes, I have noticed that particular bad behaviour, too.
With DBD::Pg and DBD::mysql.
At the same time, DBD::Oracle, DBD::InterBase and DBD::Sybase work as
expected. Rows are fetched with fetchrow...() functions instead of all
being sucked up into memory at the time execute() is called.
Anybody know why is that happening?

What bothers me is different behaviour of different DBD drivers. But,
yes, I have just subscribed to dbi-users list which is the right place
to ask that question.
