Hi!
I like the idea of having a standard function which shows a TOAST value ID
for a row. I've used my own to handle TOAST errors. Just, maybe, more correct
name would be "...value_id", because you actually retrieve valueid field
from the TOAST pointer, and chunk ID consists of valueid + chunk_seq.
