"UPDATE table_name SET w = $1, x = $2, z = $4 WHERE y = $3 RETURNING *",

"UPDATE table_name SET w = $1, x = $2, y = $3, z = $4 RETURNING *",

I know it’s too late to be helpful now, but I always write the WHERE first, because you are not the first person to have done this…
This was the first thing I was taught when writing queries.
Roll the statements uphill so the last thing you do is the select.
