Hi, What'st the current state of play with indexes and ON CONFLICT ? The docs seem to vaguely suggest it is possible, but this SO 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 it in a function ? ON CONFLICT (index_name) .... : does not work ON CONFLICT ON CONSTRAINT index_name....: does not work
