In pl/pgsql if you do not use an "INTO" clause on a select statement you
must replace the "SELECT" with "PERFORM". Failing to do so results in the
error you are seeing. In this case your calls to the sub-function do not
magically populate the parent function variables. You must manually map the
output of the sub-function call query onto the parent variables.
