Hi.

It is my understanding that only tables can exist in the
'pg_publication_rel' catalog.

e.g. only for these scenarios:
* included tables - when pg_publication.puballtables is false, these
are the specified FOR TABLE ... tables
* excluded tables - when pg_publication.puballtables is true, these
are the specified FOR ALL TABLES EXCEPT (TABLE ...) tables

In particular, AFAIK there is no way for sequences to be in the
'pg_publication_rel' catalog. e.g.
PG19 only supports "CREATE PUBLICATION ... FOR ALL SEQUENCES", which
is indicated by pg_publication.puballsequences.
PG19 has no support for "CREATE PUBLICATION ... FOR SEQUENCE seq1,seq2".

~~

Meanwhile, the DOCS page for 'pg_publication_rel' catalog [1] since
commit 55cefad says that sequences are also possible [2]:
------
prrelid oid (references pg_class.oid)
Reference to table or sequence
------

How are sequences possible? PSA a patch to correct it.

Or, am I mistaken here?

You are right, pg_publication_rel can never have a seq entry while
pg_subscription_rel can have. The patch LGTM.
