I was told that application inserts rows into given table with queries like:
INSERT INTO zz (id, body) VALUES (?, ?) ON CONFLICT (id) DO NOTHING
inside transaction. It's possible to attempt to insert row with same id
several times inside one transaction (in that case usually that id is
new one i.e. was not presented in the table before that transaction).
Hope it could help in some way.
