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,
if any required rows get removed on standby, the slot gets dropped.

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

Thank you,
