Yes, I've thought about ignore errcontext by considering elevel. But I
scratched the source code for other uses of errcontext, and I found seems
all of them understand that errcontext will be called unconditionally. For
example, buffer_write_error_callback(), it doesn't say "error in writing
block ..." but says "writing block ...". So I think this place is not
consistent with others - it just says "invalid ... ", and should be changed.
