How about this: we can just lower the elevel, from NOTICE to DEBUG1.
We'd then be able to keep the message we have today in
verify_nbtree.c. We'd also add a matching message (and logic) to
verify_heapam.c, keeping them consistent.

I find your argument about spammy messages convincing. But it's no
less valid for any other user of amcheck. So we really should just fix
that at the amcheck level. That way you can get rid of the call to
pg_is_in_recovery() from the SQL statements in pg_amcheck, while still
fixing everything that needs to be fixed in pg_amcheck.
