Existing functions saves at public schema.

I have a Postgres DB. And there are many functions. I need to refactor it but when I open them in 0xDBE they are without schema name. And after save I have one new function in public schema. How to say IDE to open functions with schema name.
Example how should be

CREATE OR REPLACE FUNCTION schema_name.function_name()

How it in 0xDBE

CREATE OR REPLACE FUNCTION function_name()
