Hi Amit,

I am reading about this feature and reviewing it.
To start with, I reviewed the patch: 0005-Doc-changes-describing-details-about-logical-decodin.patch. 

>prevent VACUUM from removing required rows from the system catalogs,
>hot_standby_feedback should be set on the standby. In spite of that,

IIUC, you mean `if any required rows get removed on *the master* the slot gets
dropped`, right?

Thank you,
