+A _real_ quick blog post just to record a useful technique I just discovered that I'll want to have a record for in the future - if inserting into a Postgres table, so long as you're on `>9.5`, you can upsert-and-overwrite with the following syntax:
+<!--more-->
+```sql
+INSERT INTO tablename (a, b, c) values (1, 2, 10)
+ON CONFLICT (a) DO UPDATE SET a = EXCLUDED.a, b = EXCLUDED.b, c = EXCLUDED.c;
+```
