The v11 version of this patch is causing a compiler warning for me:

In file included from heaptuple.c:58:
heaptuple.c: In function 'missing_hash':
heaptuple.c:97:3: warning: implicit declaration of function 'hash_any'; did you mean 'hash_stats'?
[-Wimplicit-function-declaration]
   hash_any((const unsigned char *) entry->value, entry->len));
   ^~~~~~~~
../../../../src/include/postgres.h:471:38: note: in definition of macro 'DatumGetUInt32'
 #define DatumGetUInt32(X) ((uint32) (X))
                                      ^

It seems to work anyway, but please fix.
