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.

Best regards,

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
