I think it refers to the Extended Query support in the frontend / backend protocol, as in the documentation:
http://www.postgresql.org/docs/8.4/static/protocol-flow.html#PROTOCOL-FLOW-EXT-QUERY
The extended query protocol breaks down the above-described simple query protocol into multiple steps. The results of
preparatorysteps can be re-used multiple times for improved efficiency. Furthermore, additional features are available,
suchas the possibility of supplying data values as separate parameters instead of having to insert them directly into a
querystring
So that's for parse/bind/execute communications, which are used in prepare/execute and queryParam I think.
