Question: Can someone please decipher while rechecking updated tuple for me?

ERROR:  deadlock detected

DETAIL:

    Process 31391 waits for ShareLock on transaction 770573675; blocked by process 25788.

    Process 25788 waits for ShareLock on transaction 770573695; blocked by process 31391.

    Process 31391: update my_table row_to_update set col_to_update = now() from (select id from my_table where col_to_update is null order by id limit $4 for no key update) matched_row_to_update where row_to_update.id = matched_row_to_update.id returning row_to_update.id as id, row_to_update.col_to_update as col_to_update, , row_to_update.other_col as other_col

    Process 25788: update my_table set col_to_update=$1 other_col=$2 where id=$3

HINT:  See server log for query details.

CONTEXT:  while rechecking updated tuple (36328,33) in relation "my_table"

I found the it here but couldn't figure it out what exactly is happening there. what is the lock? and how can I debug/resolve it?

A little background:

previously we had deadlock errors with the message: while updating tuple (xxx,xxx) in relation my_table between the two transaction with the same query (the first query in the above). We managed to solve it by adding order by id for no key update. But now, it's a new deadlock which I can't resolve.
