If you are chasing performance with the binary protocol you might want
to take a look at libpqtypes: http://libpqtypes.esilo.com/
It facilitates fast communication to/from the database. For
inserting, you stack an array of composites locally and send it to the
database with a single query and the receiving side can unwrap it and
do the insert in a function. Advancements in json handling have
largely displaced this kind of usage in many situations but if you
have extreme performance requirements it's still worth a look.
