Getting name of the current function inside of the function with plpgsql

Question

Is there anyway from within a plpgsql function that you can get the name of the function? Or even the OID of the function?

I know there are some \"special\" variab

Answer 1

As of Postgres 9.4, the below function will return its own name:

CREATE OR REPLACE FUNCTION your_schema.get_curr_fx_name()
RETURNS text AS  $$
DECLARE
  stack text; fcesig text;
BEGIN
  GET DIAGNOSTICS stack = PG_CONTEXT;
  fcesig := substring(stack from 'function (.*?) line');
  RETURN fcesig::regprocedure::text;
END;
$$ LANGUAGE plpgsql;
