What should this "select count(*) from xx;" be good for, if
you don't want to use the result? You can of course do
"perform select ..." because that'd use another PL/pgSQL
executor construct that doesn't complain about getting an
unused return value, but I still wonder why you want to waste
CPU and IO (bought an oversized system?).
