I agree with you. But we don't have even enough time for development.
Could you maintain the documentation? Or is here someone who could
maintain the documentation?
There is config.html in CVS (I hope Dave put it into releases too)
so you could study from it.

It was broken some time ago. And no every user need it. When you access
whole table it doesn't matter if you use "use declare/fetch" or not.
Then you have turned on "use declare/fetch" you don't know number
of returned rows until you reach end of result.
It isn't so clear to enable it by default.

Hey, does I miss something? There is no support for updateable cursors
in 08.01 psqlodbc driver. And it is marked as experimental feature in
07.03 version.
