Can you explain exactly what you are trying to do and why? You are getting
the error because a SQL function does not RETURN, it must end with a
SELECT statement. It also has no DECLARE, BEGIN, or END. You can either
remove all of those or change the language to plpgsql. See:
http://www.postgresql.org/docs/7.3/static/xfunc-sql.html
In addition, you cannot (with SQL) use an argument as the tablename. You
also probably want to use EXISTS, not "count..::bool".
