Re: Regarding: Replication of TRUNCATE commands is not working

Hi Laurenz,
Thanks for the response
Question: What PostgreSQL version are you using? The feature was
introduced in v11.
Answer: I am using the 16.0 Postgresql version.
db1=> SELECT version();
version
-----------------------------------------------------------------------------------------------------
PostgreSQL 16.0 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu
7.5.0-3ubuntu1~18.04) 7.5.0, 64-bit
(1 row)

Question: How exactly is the publication defined? Perhaps TRUNCATE is
excluded.
I am not using the subscribe/publication model . but i have created a
replication slot on the source database and then i am calling below
procedure to get the details from replication slot:
select data from pg_logical_slot_peek_changes('db1_slot', NULL, NULL,
'pretty-print', '1');

In the case of TRUNCATE , the above procedure does not show up any records.
however this procedure shows up insert, update and delete events.

As you mentioned TRUNCATE is excluded, is there any way to exclude
TRUNCATE ?

Thanks
Arvind
