Defining global constants in Postgresql stored function/procedures? -

i have set of functions have created in postgresql. able configure behavior , limits global constants.

so far, have implemented functions these, functions call retrieve constant value:

create or replace function slice_length() returns integer $$ begin     return 50; end; $$ language plpgsql immutable;

i wondering, there better/smarter way achieve this?

take @ other answer. uses same approach do.
