I migrated a project from RethinkDB to Postgres and replaced the changefeeds with a trigger that uses NOTIFY, does the same thing except that with the changefeeds I had the diff and with this trigger I still have to re-fetch the row and compare the diff.

Something that RethinkDB supported natively :(
