If you have certain rule for naming those writing functions and the
rule can be described in regular expressions, then you can write the
regular expressions in black_function_list.

Another idea is, using white_function_list instead of
black_function_list. This may give a false positive (i.e. a read only
function which is not in the white_function_list is routed to primary
PostgreSQL server), but it will not give any error.
