Certainly, but once you've compared the first byte you can handle any
remaining bytes via the main loop.  And in fact the code is already
depending on being able to do that --- the use of CHAREQ rather than
BYTEEQ is just wasted cycles.

+1, I think, but I wonder why we had the duplication in the first
place.  Is there any likelihood that bytea's semantics should diverge
from the text case?
