The description you quote doesn't appear to have much of anything to do
with the actual behavior of 7.4.

7.4 will trim trailing spaces when converting char(n) to varchar or
text, but the example query does not do that. It just coerces query
output columns to char(n), and that works the same as it did before.
For instance

regression=# select 'zit'::char(77);
bpchar
-------------------------------------------------------------------------------
zit
(1 row)
