AFAICS we have no realistic choice other than to reject \0 in SQL
literals; to do otherwise requires API changes throughout that stack of
modules.  And once you admit \0 is no good, it's not clear that
\somethingelse is any better for bytea-using clients.  Moreover, given
that we are moving away from backslash escapes as fast as we can sanely
travel, expending large amounts of energy to make them work better
doesn't seem like a good use of development manpower.

Haven't looked at your test case yet... but it sure looks to me like the
COPY code *ought* to cover this.
