Hi,

Are there any built in or known structures I can use in Postgres to represent a family tree?

The usual tree representations in SQL are for regular hierarchy of data, but on a family each node had usually 2
parentsand a few child nodes. What will be the best way to represent something like this in an efficient manner? 

Guy.
