It seems to me that postgres is trying to do as you suggest: text is
characters and bytea is bytes, like in Java. You don't indicate what
version you are using, this area was rejigged recently.
The most surprising this is that to_ascii won't accept a bytea. TBH the
whole to_ascii function seems somewhat half-baked. If what you're
trying to do is remove accents, there are perl functions around that do
that. Basically, the switch to a different normal form then drop all
the accent characters.
Essentially, Postgres supports UTF-8, but doesn't understand Unicode
characters much at all.
Have a nice day,
