pg15 beta2 bug:cause by logcial replation
hello,:
i am jerome Peng, from pg15 beta2 changes since beta 1 , i test this item and found a error:
pg_publication_tables now provides information on column lists and row filters.
\c logical_src
create table tab1(id int primary key,info varchar);
create table tab2(id int primary key,info1 varchar,info2 varchar);
select pg_create_logical_replication_slot('logical_slot1','pgoutput');
create publication pub_two for table tab1, tab2;
\c logical_dest
create table tab1(id int primary key,info varchar);
create table tab2(id int primary key,info1 varchar,info2 varchar);
create subscription sub_two
connection 'hostaddr=127.0.0.1 port=1501 user=postgres dbname=logical_src'
publication pub_two with(create_slot='false',slot_name='logical_slot1');
ERROR: could not receive list of replicated tables from the publisher: ERROR: column t.attnames does not exist
LINE 2: , t.attnames
Test is ok in pg15 beta1.

Hi,
I tried your reproduction steps but cannot get the same error.
Can you please provide some more information about the version
of publisher and subscriber you used ?
Just to confirm, did you use the PG15 beta1 or earlier PG15 version
as the publisher and use PG15 beta2 as the subscriber ?
Best regards,
Hou zj

It looks to me like this was an attempt to replicate from 15beta1 to
15beta2, which would fail because commit fd0b9dceb imagines that any
server reporting version >= 15 will have pg_publication_tables.attnames,
even though that column was not there in beta1.
I bitched about the ill-timing of that schema change at the time
but was outvoted. At this point I think it's water over the dam.
We could perhaps change that test in fetch_table_list(), but it'd
require access to the source server's catversion, which I don't think
is readily available. In any case, by the time we could provide a fix
it'd be useless to testers of beta1; they'd have updated already by
some other method.

Obviously in the same pg server pg15 beta2, because my
subscriber creation use "create_slot='false'", another clue is i use "\c", all the test on the same cluster.

Hmm, if both publisher and subscriber are on PG 15beta2, I am not sure why you get this error.
Can you please try to Initdb a new database and try the reproduction steps again ? It’s
possible that there is something wrong when initializing the database.

yes，the problem was i use port 1501 when i create subscription. so the problem is use the PG15 beta1 as publisher, and use PG15 beta2 as the subscriber.
