Description:

Good Morning,

i'm facing the following issue:
i have a publication (pub1) with publish of insert and update transactions
made on table tab1 .
if i update tab1 with the following statement:

update tab1 set field1 = 'value2' where field1='value1';

logical decoding on subscriber process read the transaction , and following
the guidelines of  "31.3.3. UPDATE Transformations"  (

https://www.postgresql.org/docs/current/logical-replication-row-filter.html#LOGICAL-REPLICATION-ROW-FILTER-TRANSFORMATIONS
) , the subscriber try as first thing the delete of old row and then the
insert of the new row .

What i think is a bug ,  is that the delete on old row is never done unless
you specify publishing deletes on publications.
So not all updates are published on subscriber unless you explicitily set
publish deletes on publisher.

Regards,

Daniele
