array[10] - Mailing list pgsql-admin

hi there,

i have got a problem concerning arrays in postgres
i created a function in which i want to know if the index 8 of var_array
ist not NULL:

IF var_array[8] IS NOT NULL

    THEN

    (query)

    END IF;


then i call the function and the query is submitted, allthough
var_array[8] is 'NULL'



any solutions for that problem?

thanx!
