You seem to be on the right track. > Now obviously I have to add the proper code to the functions, but the > version of the code I have for the PR-Tree is in C++. Is there a way > to implement the functions using the existing PR-Tree code in C++? No, we don't support C++ in the backend. It's almost certainly easier to just start from scratch anyway, because integrating it with all the PostgreSQL infrastructure like the buffer manager, vacuum, WAL-logging, data type and operator system. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
