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 preparatory steps can be re-used multiple times for improved efficiency. Furthermore, additional features are available, such as the possibility of supplying data values as separate parameters instead of having to insert them directly into a query string So that's for parse/bind/execute communications, which are used in prepare/execute and queryParam I think. -- dim -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
