postgres function definition not saving top whitespace

For reference I am running postgres 9.6 . I'd like to write functions inside of postgres where the top of the function saves. create or replace function apqp.apqp_list_gentex_tool_report_getlist(_omni_search text DEFAULT ''::text , _cust_id integer DEFAULT 0 ) returns TABLE(reason text , program text , mold_number text , rev text , stone_part_number text , part_description text , cust_request_num text , status text ) language sql as $$ -- and so on When I build this, if I relookup the function definition in datagrip the top part loses my white space I put in there and it looks like this. create or replace function apqp.apqp_list_gentex_tool_report_getlist(_omni_search text DEFAULT ''::text, _cust_id integer DEFAULT 0) returns TABLE(reason text, program text, mold_number text, rev text, stone_part_number text, part_description text, cust_request_num text, status text, kickoff date, mold_delivered date, first_shot date, ppap_submission_date date, interim_approval_expiration_date date, tool_shop text, manager text, apqp_status text, apqp_list_id integer, comments text) language sql as $$ Is there a setting in postgres or someway to save to the database when I CREATE a function that it will save my white space at the top. I'd like to be able to repull the definition while maintaining my white space.
