What's the best way to deal with global constants in PLPGSQL. Currently I am putting them in a function with out parameters and then calling that function from every other function that needs them like this.
CREATE OR REPLACE FUNCTION hashids.constants(
OUT min_alphabet_length integer,
CREATE OR REPLACE FUNCTION hashids.constants(
OUT min_alphabet_length integer,
OUT sep_div numeric,
OUT guard_div numeric,
OUT default_steps text,
OUT default_alphabet text,
OUT salt text)
I am presuming that if I set this function as immutable the calls to this function will be cached and will not incur much overhead.
Is there a better way to deal with this?
