pg_repack is aborted with error if a publication FOR ALL TABLES exist

[Melkij]

pg_repack is aborted with error if a publication FOR ALL TABLES exists and apply_log requires deleting or updating a row in a temporary table.

Reproduction:

create table foo(id int primary key, val text);
insert into foo values (1, 'hi!');
create publication foo for all tables ;
# start pg_repack with break at rebuild_indexes
update foo set val = 'h2' where id = 1;
# continue pg_repack process and see error like this:

ERROR: query failed: ERROR:  cannot update table "table_16388" because it does not have a replica identity and publishes updates
HINT:  To enable updating the table, set REPLICA IDENTITY using ALTER TABLE.
CONTEXT:  SQL statement "UPDATE repack.table_16388 SET (id, val) = ($2.id, $2.val) WHERE (id) = ($1.id)"
DETAIL: query was: SELECT repack.repack_apply($1, $2, $3, $4, $5, $6)

It's not that difficult to format ALTER TABLE repack.table_' || R.oid || ' REPLICA IDENTITY USING INDEX index_' || PK.indexrelid in repack.tables, but for this to work, I also need to set NOT NULL on columns, which is less trivial. Furthermore, repack might break subscribers of this publication.

Given the lack of previous bug reports (this setup never worked since introduction of publications in pg10), I suggest adding a check for publications FOR ALL TABLES and simply refusing to work in such a database by default.
