Wait... Your saying your question is so complex it needs 41 pages (including graphs) to ask? I didn't bother before, but now I'm curious, I'll have to go take a look.

No, only the 25 page document (which has the graphs) is directly related to the question. It is different variants on a query (well, two queries, but they are very similar), along with EXPLAIN ANALYZE VERBOSE and time-memory graphs.

The 41 page document is just background, but relevant background. It contains information about the schema, tables, hardware, pg config info. It also has transcripts of a couple of old IRC sessions, which are increasingly less relevant, so I may remove that.

Since I've been told by a couple of different people that the way I asked my question was not ideal, I'll try reposting again with a modified version (but still containing the same information) in a bit.
