Re: [HACKERS] knngist plans
Oleg as I said I do believe some things could get better in docs. Here are 4 main drawbacks in my opinion: 1. The docs lack example(s). There are some references to gistproc.c etc but this is not part of the docs and if I am someone that has just started this is hard and confusing (I shouldn't have to read the full technical solution to another problem in order to solve mine). 2. The 7 methods are poorly explained, at least theoretically. For example when I started I couldn't understand where each function was used. I had to read papers to understand the logic. 3. Describe situations that gist can be used. I am aware of spatial indexing because I worked on it, but I have the impression that there are more (e.g. computational biology). 4. Why not add some images/figures? (1 image = 1000 words) GiST is a very important and useful part of postgresql but it's hard to get started with it. Moreover, I am sure it has capabilities, other than the profound, that are not known to many people (including me). Plus knngist will give gist a boost, and I suggest that it shouldn't be delayed any more. We have some documentation already, Teodor will post soon. I would really like to see what Teodor has done. I could also prepare a document with the additions I would like to see in docs. Shall I do it? Of course it might take a while to finish it.

Re: [HACKERS] knngist plans
Excerpts from Marios Vodas's message of sáb oct 16 11:11:52 -0300 2010: 4. Why not add some images/figures? (1 image = 1000 words) I can answer this: the reason is that we haven't settled on a technology for producing figures. There's a thread about it, but no consensus. -- Álvaro Herrera alvhe...@commandprompt.com The PostgreSQL Company - Command Prompt, Inc.

[HACKERS] knngist plans
I would like to ask in which future version of postgresql knngist is planned to be included. Is there any possibility to be included in 9.1?
