Thread: "INSERT ON CONFLICT UPDATE" - Use of indexes ?
Hi, What'st the current state of play with indexes and ON CONFLICT ? The docs seem to vaguely suggest it is possible, but thisSO question (https://stackoverflow.com/questions/38945027/) seems to suggest it is not. I've got a unique named index on a table (i.e. "create unique index xyz...") but I cannot seem to be able to refer to itin a function ? ON CONFLICT (index_name) .... : does not work ON CONFLICT ON CONSTRAINT index_name....: does not work

If you create a unique constraint, it'll create a unique index to enforce the constraint. ON CONSTRAINT requires a constraint name, not an index name. David
