I wonder if these should say "Sets the amount of time to wait [before]
authentication during connection startup"

Should this still say "seconds" ?
Or change it to "this amount of time"?
I'm not sure.

Actually, I think that for log_rotation_size, it should not say "forcing".

"Sets the maximum size a log file can reach before being rotated"

BTW the EXPLAIN flag for enable_incremental_sort could be backpatched to v13.
