There is no single .h file that will tell you everything you need to know. I'd suggest starting here: http://developer.postgresql.org/pgdocs/postgres/internals.html with particular attention to chapter 48 http://developer.postgresql.org/pgdocs/postgres/indexam.html After that the indexam README files might be educational: src/backend/access/nbtree/README src/backend/access/gin/README src/backend/access/gist/README src/backend/access/hash/README and then start looking at .h files. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
