I think it is. LIST EXTENSIONS provides a way to ensure what is there and
to know what options are available. It should *NOT* be a way of switching
extensions on and off.

I'm not sure where you're coming from here. I'll re-read the thread that
seems to have developed overnight on pipelining and see if it helps. Also
the one on caching the results.

But right now I think you're trying to solve a problem in the wrong way and
breaking things as a result.
