Problem description: | |
A query of the form select ... from where some_udr(col_x) IN () or some_udr(col_y) IN () ... potentially and temporarily, for the duration of the query, will consume large amounts of memory, depending on how many rows hit, how many such in clauses and how long each . More condtions for this problem are: - functional indices existing on some_udr(col_X) - a query plan chosen that's making use of these indices (OPTCOMPIND 0 can be a favoring factor) | |
