Hi List,
I am doing a INSERT...ON CONFLICT...UPDATE.. on a table. The query is
mostly-UPDATE and does not change any columns most of the time, like
so:
CREATE INDEX ON book(title);
INSERT INTO book (isbn, title, author, lastupdate) VALUES ($1,$2,$3, now())
ON CONFLICT (isbn) DO UPDATE set title=excluded.title,
author=excluded.author, lastupdate=excluded.lastupdate;
PostgreSQL seems to consider the title as changed and refused to do a
HOT-update. It works if I remove the `title=...` part.
Are there any tricks to make it smarter? The title don't change most
of the time after all.
Regards,
Daniel
