There was a question last meeting with regards to
PostgreSQL and the consensus seemed to be that it wasn't
up to the job of handling GIS. I did a few performance
tests on my laptop and didn't find it all that bad,
I guess it would be interesting to race it off against
other indexing systems on the same hardware but my
results are really just scratching the surface of all
the tests that could usefully be done.

I did notice that the R-Tree performance is somewhat
data dependent although I'd like the chance to go into
that in a bit more detail. I'll add to the page when
I've run a few more tests... I remember someone saying
that they had the loan of a kick-arse server as a test
bench (was it Matt? can't remember) if anyone wants to
lend me an account on a test machine I can chug my
test scripts across and give it a run to produce some
comparison graphs (current test is only on my laptop
which obviously has its limitations).
