Hmm. I though TOAST is only applied to single values, not the entire tuple (row)?
As each column is substantially shorter than the TOAST threshold, I would not expect toasting to kick in here.
Well, the entire tuple would be 25600 bytes plus some overhead, which
cannot fit on a Postgres page (8K, unless the OP changed compile options
without mentioning it). So something has to be done to make it fit, and
that something is going to be toasting any fields that can be toasted.
Ah, obviously.
Thanks
