pgbench stops the script on errors. If the script was reduced to
select 1/0;
DO $$BEGIN RAISE NOTICE 'print this; END; $$
the DO statement would not be executed either.
When the error happens inside a pipeline section, it's the same.
The pgbench code collects the results sent by the server to clear up,
but the script is aborted at this point, and the DO block is not going
to be sent to the server.
