I don't actually have a problem with depending on the internal
representation of bytea. What I'm unhappy about is that (despite
Caleb's assertions that this is only about bytea) the patch proceeds
to make plpython intimate with the internal representation of a bunch
of *other* datatypes, some of which we have good reason to think may
change in future. If it were only touching bytea I would not have
complained.
