This appears to be a classic example of:

#

Casts to text that formerly occurred implicitly may now need to be
written explicitly

Data types other than char and varchar are no longer implicitly
castable to text, except in the limited case of a || (concatenation)
operator whose other input is textual. While this will require explicit
casts in a few queries that didn't need them before, the elimination of
surprising interpretations justifies it.
