Hi, if I read https://www.postgresql.org/docs/9.6/static/sql-insert.html correctly there can be only one conflict target or none at all.
What if I have a table with 3 unique constraints? If the first one is violated by the insert I want to do nothing. If the 2nd is violated some fields should be updated. And violation of the 3rd one should raise an error. Can that be expressed? Thanks, Torsten
