I hope this comes out readable. If not I can do a separate attachment. I notice it says 'BEFORE INSERT'. Maybe that should be after?

Your function name does not match up with the code on the site, so we
will need to see the actual trigger/function.
In psql do:
\d entry
to see the trigger definition and then post it here.
Also from that definition you can get the function name.
Again in psql do:
\ef fnc_name
to confirm the function is the one you think it is.
Would also be helpful to see the script you wrote to do the bulk insert.
