Well, this is independent of the proposed patch, so I think a separate
thread is okay. The question is "shouldn't bytea_output be marked
GUC_REPORT"? I think that probably it should be, though I wonder
whether we're not too late. Clients relying on it to be transmitted are
not going to work with existing 9.0 or 9.1 releases; so maybe changing
it to be reported going forward would just make things worse.
