Thread: Replication slot dropped in Bidirection rep: column addition

Hi Team,

I noticed replication drops while adding column to the table in postgres16.

There is not much delay in adding column to the both servers.

Here are the steps to reproduce:

Server1: 
    --run infinite loop tx with each loop commit and delay for 3 sec
    --another session ran the following column addition 
ALTER TABLE customers  
ADD COLUMN phone VARCHAR(25); 


Server2: 
    --run infinite loop tx with each loop commit and delay for 3 sec
    --another session ran the following column addition 
ALTER TABLE customers  
ADD COLUMN phone VARCHAR(25); 


Please let me know if this is a bug in postgres16 or Am I missing something?

Due to this issue ,I am planning to disable subscriptions while adding new columns ?

Thanks,
Ravi
