Hmm, when I do the above on 15.14 I get:

-[ RECORD 1 ]-------+-------
indexrelid | 242209
indrelid | 242205
indnatts | 1
indnkeyatts | 1
indisunique | t
indnullsnotdistinct | f
indisprimary | t
indisexclusion | f
indimmediate | t
indisclustered | f
indisvalid | t
indcheckxmin | f
indisready | t
indislive | t
indisreplident | f
indkey | 1
indcollation | 0
indclass | 3124
indoption | 0
indexprs | NULL
indpred | NULL

What is full(15.x) version of Postgres are you using?

Is it the community version or a fork or SaaS?

What do you get for queries below?:

select * from pg_opclass where oid = 3124;

select * from pg_opclass where opcname = 'int8_ops';

Per a comment from Ron, does this lack of export happen every time you
dump the table?
