Any way to make PG driver obey PrintWarn?

I'm using the DBD::Pg driver and i've specifically turned "PrintWarn" off,
yet I am still getting spammed with messages like this:

NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "aus_flag_pkey" for table "aus_flag"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "aus_password_crypt_pkey" for table "aus_password_crypt"

etcetcetc...

rt.cpan.org doesn't show any active bugs about this. Is this a known issue?
Is it even a bug or am I doing something wrong? Why does Pg feel it
neccessary to tell me that these implicit indexes are being created anyways?

    Thanks,
        Tyler
