Eh... good morning folks. I have been lurking on the postgreSQL lists
for a while. Now when I read this, a question arise.
Does postgres calculate some sort of a "checksum" over a row?
I mean... storing whether a field is NULL or not inside a single bit,
seems slightly risky (especially when we consider how much of the
hardware out there, is of marginal quality).
Would it be worth it to calculate some sort of a checksum over a row, and
store that checksum along with the row?
