We're talking about code which is recompiled for a new version of Postgres but
not altered to return the recheck flag for every tuple? Can we rig the code so
it effectively returns recheck=true all the time in that case? If so then it
would be safe to ignore the recheck flag on the opclass.
There's no danger of picking up code which was actually compiled with older
header files after all, the magic numbers wouldn't match if it's V1 and in any
case I would expect it to crash long before any mistaken tuples were returned.
