I think this could use some wordsmithing; I didn't like listing the
parameters explicitely, and Jaime Casanova suggested not using the terms
"inherit" and "parent table" in this context. So I came up with this:

Note that the TOAST table uses the parameter values defined for the main
table, for each parameter applicable to TOAST tables and for which no
value is set in the TOAST table itself.

Thoughts?
