Hi
LogicalIncreaseRestartDecodingForSlot() has a debug log to report a

Here's a patch to add the same.

Subject: [PATCH 1/2] Report new catalog_xmin candidate in
LogicalIncreaseXminForSlot()
Similar to LogicalIncreaseRestartDecodingForSlot() add a debug message
to LogicalIncreaseXminForSlot() reporting a new catalog_xmin candidate.
We should submit this to the community.
