Re: BUG #19093: Behavioral change in walreceiver termination between PostgreSQL 14.17 and 14.18

Hi Xuneng and Michael,

Thank you so much for the quick response and for fixing the issue. I saw
that the commit has already been merged into master.

I’d like to ask whether this fix will be included in the patch release for
version 14 - specifically 14.20. I noticed the commit mentions
Backpatch-through: 13, and I want to confirm whether that means the fix
will be backpatched to version 13 and all subsequent supported versions.

Thanks again!

Best regards,
Xingguo
