Why would very large text values effect the speed of a seq scan that does not actually evaluate those values?

I'd actually suppose it's the smaller values (up to a few hundred bytes)
that impact this the most.  Really wide fields would be pushed
out-of-line.

Meaning that the portion of the text value stored in the companion TOAST table would be ignored for this type of query, correct? That's why I'm concerned.

How much of a TOAST'd field is actually stored in the main heap table? Is there a way to configure that amount?
