How about providing a mechanism people can use to confirm a person's certification. Make that part of being certified.
The company could advertise having people certified for postgresql, and their customers could check and verify that the person they are working with is certified. Perhaps, make a requirement for companies advertising in that manner to provide a link/button/etc. someplace on their site that links back to the confirmation site for postgresql people.
Of course, if the list of certified people is open, then it could be up to the certified person to list his/her company information, and then the certification confirmation site could provide a search function. The button/link on a "certified" company might link back with a prebuilt search query to list their people.

Most companies don't want to make their employee list public.
