FWIW, works for me:

testdb=# SELECT * FROM pg_decoding_slot_get_changes('regression_slot', 'now', 'include-xids', '0');
location | xid | data
----------+-----+------
(0 rows)

testdb=# BEGIN; INSERT INTO data(data) VALUES('1'); INSERT INTO data(data) VALUES('1'); COMMIT;
testdb=# SELECT * FROM pg_decoding_slot_get_changes('regression_slot', 'now', 'include-xids', '0');
location | xid | data
-----------+------+------------------------------------------------
0/2B81ED0 | 1973 | BEGIN
0/2B823A8 | 1973 | table "data": INSERT: id[int4]:14 data[text]:1
0/2B823A8 | 1973 | table "data": INSERT: id[int4]:15 data[text]:1
0/2B823A8 | 1973 | COMMIT
(4 rows)

testdb=# SELECT * FROM pg_decoding_slot_get_changes('regression_slot', 'now', 'include-xids', '0');
location | xid | data
----------+-----+------
(0 rows)

( output of "SELECT * FROM pg_replication_slots;" is, indeed, out-of-date.)
