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

does not do the same as

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

It’s 2 am and my mind blanked out the WHERE, and just wanted the numbers neatly in order of 1234.

idiot.

FML.

      Transactions aren’t backups. You can just as easily commit before fully realizing it. Backups, backups, backups.

        Yes, but

        1. Begin transaction
        2. Update table set x=‘oopsie’
        3. Sees 42096 rows affected
        4. Rollback

        Can prevent a restore, whereas doing the update with auto commit guarantees a restore on (mostly) every error you make
