Postgres UPSERT native support

Looks like Postgres recently added UPSERT (9.5alpha is it?). Seems Sequelize handles psql upsert fine presently with its workaround, so obviously no rush.

Me personally (and maybe I need re-architecting), my current project’s most common SQL operation is UPSERT. That operation seems quite slow; this is the resultant SQL which looks like it would be slow:

CREATE OR REPLACE FUNCTION pg_temp.sequelize_upsert() RETURNS integer AS $func$ BEGIN INSERT INTO ... VALUES ...; RETURN 1; EXCEPTION WHEN unique_violation THEN UPDATE ... SET ... WHERE ...; RETURN 2; END; $func$ LANGUAGE plpgsql; SELECT * FROM pg_temp.sequelize_upsert();

So I’d personally upgrade to Postgres 9.5 if native upsert becomes supported in sequelize

This is a really stale issue. Is there any update on this?

Well, PostgreSQL 9.5 is released.
