How do you execute a postgresql function from perl?

I'm trying to execute a postgresql function from perl. The function 
inserts data into two different tables. I prefer this a sopposed to 
using two insert statements. Can anyone point me to any information at 
all on how to execute postgresql functions from Perl? The code for 
Oracle doesn't work. Any help would be appreciated.
