Right.  The parameters will either be sent out of line which won't require
escaping or for the V2 path they will be sent in the query, but it isn't
the array or bytea codes' responsibility to escape them correctly.  The
code in core.v2.SimpleParameterList@setStringParameter should handle that
for us.
