Primary opclass members are stored right in the Relation data struct for
you.  Since (I trust) you're only supporting this for btree, you could
just use rd_supportinfo[0] which will not even cost an fmgr lookup.
See index_getprocinfo() and callers.

There's currently no reason to limit HOT to b-trees.

How about just doing a memcmp? That would be safe, simple and fast and covers all interesting use cases.
