SPI_ERROR_CONNECT

I am receiving a SPI_ERROR_CONNECT error. From what I'm reading I could
fix this in C using SPI_push(). How does one fix this with PL/PGSql?

Return error:
---------------------------------------------------------------------------------------------------
NOTICE: current day = 1

ERROR: SPI_connect failed: SPI_ERROR_CONNECT
CONTEXT: PL/pgSQL function "pop_tag_day_over" line 17 at FOR over
SELECT rows

********** Error **********

ERROR: SPI_connect failed: SPI_ERROR_CONNECT
SQL state: XX000
Context: PL/pgSQL function "pop_tag_day_over" line 17 at FOR over SELECT
rows
---------------------------------------------------------------------------------------------------

Here is my function:
---------------------------------------------------------------------------------------------------
CREATE OR REPLACE FUNCTION pop_tag_day_over()
RETURNS void AS
$BODY$
DECLARE
current_row RECORD;
trans_day integer;
BEGIN
trans_day := 0;

truncate table day_over;

FOR i IN 1..(extract('day'
from(last_day(process_month())))-1)::integer LOOP

execute 'CREATE OR REPLACE VIEW temp_tags_18 AS SELECT datetime,
tagnum, tagtype, vrn
FROM tag
WHERE datetime <= process_month()
AND datetime > (process_month() - 18 + ' || trans_day || ')
ORDER BY vrn, tagnum, datetime';

FOR current_row IN SELECT * from temp_tags_18_counted
LOOP
IF current_row.day_count = 1 THEN

insert into day_over (vrn,process_day) values
(current_row.vrn,(1 + trans_day) );

END IF;
END LOOP;
raise notice 'current day = %',trans_day+1;
trans_day := i;

END LOOP;

END;
$BODY$
LANGUAGE 'plpgsql';
