Don't know, and apart from that, there will be no data added anymore to this table, seems this db will remain static
(it'sonly a few rows btw)

Well, yes, until I do the rebuild and then the issue is fixed.

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';

Might be a good idea to find out.

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