Ok. It won't help all that much on 9.0, though.
Well, it won't help GIST much, but the actually-reported-from-the-field
case is in btree, and it does fix that.
It occurs to me that if we're sufficiently scared of this case, we could
probably hack the planner (in 9.0 only) to refuse to use GIST indexes
in hot-standby queries. That cure might be worse than the disease though.
if anything, it should be documented. if you do this kind of thing
people will stop installing bugfix releases.

How about displaying a warning, when people try to use the 'feature', as
well as document it?
Cheers,
