please do so, along with your trigger definition. Are you aware that you
can define your update trigger to fire on a specific column?

https://www.postgresql.org/docs/current/sql-createtrigger.html

For UPDATE events, it is possible to specify a list of columns using this
syntax:

UPDATE OF column_name1 [, column_name2 ... ]
