TOAST table names

Is there a big reason why TOAST tables are called such cryptic names?

e.g. pg_toast.pg_toast_16399

Wouldn't it be more pleasant to have them called the same thing as their
parent

e.g. pg_toast.<name>_toast

This would be very convenient for most purposes, though it would mean
we'd have to do something when
- we rename a table
- we have very long table names
...neither of which seems like such a huge pain.

It might seem like an idle moan, but the names leak out in all sorts of
places like stat tables, logs etc so converting the names to something
useful in all cases is annoying.

Alternatively, would it be possible to have bothRelationGetRelationName(onerel)RelationGetRelationDisplayName(onerel)
the second of which would do the lookup for use in various places?
That would change lots of code however.

Comments?
