Don't know about documentation...

But I can say that IBM's Mark Anderson told me personally
"A long long time ago we decided that if an update was being performed but
nothing changed that we would bypass the
journal entry in the interest of performance (especially if journal
entries were
being sent to a backup system using logical replication)."

In my case, we noticed that AFTER triggers were be fired with no
corresponding journal entries.

I thought I read somewhere that the journal will only contain entries for
rows that had _actual_ column changes... is this correct? can someone
point me to the document that states this?
