That seems broken, because it's pointless to leave out a class of errors
from ERROR. Presumably the purpose of ERROR is to enable
error checking like:
\if :ERROR
... error processing
\endif
Now if you download data with SELECT or COPY and we can't even
create the file, how is that a good idea to intentionally have the
script fail to detect it? What purpose does it satisfy?

ERROR is set by SetResultVariables(PGresult *results, bool success)
and takes the value of "success", ignoring the PGresult.
So why is ERROR independant of the SQL result, relatively to your
claim that it should never reflect anything else?
