Took me a couple tries to get this right bc I kept screwing up alphabetical order 😝

[vmuriart]

scared me for a minute with that 1.22% coverage drop.
I'm not familiar with Postgresql, any concerns or possibility of returning(...) to be parsed as a function? I'm not even sure if that's valid syntax on postgresql

[darikg]

It doesn't use function syntax. It looks like this:

INSERT INTO foo (x, y) VALUES (1, 2, 3) RETURNING x, z
or DELETE FROM foo WHERE bar > 3 RETURNING baz, qux
