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.
Regards, Faheem.
