Re: Queries 15 times slower on 8.1 beta 2 than on 8.0

Jean-Pierre,

First off, you're on Windows?

Well, this is your pain point.   Can we see the index scan plan on 8.1?
Given that it's *expecting* only one row, I can't understand why it's
using a seq scan ...

> time=0.000..0.000 rows=1 loops=1)"
> "  ->  Nested Loop Left Join  (cost=0.00..5.48 rows=1 width=4) (actual
> time=0.000..0.000 rows=1 loops=1)"
> "Total runtime: 0.000 ms"

Feh, this looks like the "windows does not report times" bug, which makes
it hard to compare ...
