if you execute pdnsutil w/o any options it lists all available commands.
There you can find:

"increase-serial ZONE    Increases the SOA-serial by 1. Uses SOA-EDIT"

As far as I know this can be found in the table "records", column "content",
for every entry of the type "SOA". It corresponds to the provided serial number
you get with   "dig <zone> SOA"   (if no DNSSEC is active).
