I've been thinking a lot about it. I haven't completely ruled it out,
but there are a few cases in which having different oids for the same
query gets in the way. One that comes to mind is with prepared
statements, either explicit (which I haven't exposed yet, but it's
like the #1 request for a new feature), or implicit (currently using
them to implement 'executemany()'). However I might be overestimating
these issues, yes.

I guess I should give an overview of the whole adaptation system: I'll
try and write its documentation in the next few days. I have to start
with the documentation somewhere...
