Add support for ON CONFLICT DO NOTHING in Postgres.
Will this get merged? Any obvious show-stoppers? Full support for ON CONFLICT is pretty complex. Take a look at this: https://www.postgresql.org/docs/9.5/static/sql-insert.html This feels like a stop-gap implementation. I'd prefer t be comprehensive in implementing this feature, so I'm closing this.
I saw in the documentation there is a plan to add support for Postgres 9.5's ON CONFLICT DO UPDATE (i.e. upsert), but I didn't see any mention of ON CONFLICT DO NOTHING. This is one simple way to support the latter, although it does not support adding a **_conflict_target_**.
