Hi,

Currently the end-of-recovery checkpoint can be much slower, impacting
the server availability, if there are many replication slot files
XXXX.snap or map-XXXX to be enumerated and deleted. How about skipping
the .snap and map- file handling during the end-of-recovery
checkpoint? It makes the server available faster and the next regular
checkpoint can deal with these files. If required, we can have a GUC
(skip_replication_slot_file_handling or some other better name) to
control this default being the existing behavior.

Thoughts?

Regards,
Bharath Rupireddy.
