Accessing postgres in perl app using ssl authentication

Hello

I know this isnt specifically a postgres question, but people here are much more likely to have an answer than on a
perllist.  I have an app in perl that uses DBD::Pg to access the database.  This module does not seem to have support
forusing certificate authentication.  I'm hoping someone here might be aware of a module that does support this option. 

TIA
