New functionality of plpgsql_extension

I am working on new release of plpgsql_check extension - https://github.com/okbob/plpgsql_check.

Interesting new function is possibility to return list of used relation and functions. With these information is easy to generate dependency graph:

postgres=# \sf fx
CREATE OR REPLACE FUNCTION public.fx()
 RETURNS void
 LANGUAGE plpgsql
AS $function$
begin
  perform upper(((plus(a) + 200) * 100)::text) from xx;
end;
$function$
postgres=# select * from plpgsql_show_dependency_tb('fx()');
┌──────────┬───────┬────────┬──────┬───────────┐
│   type   │  oid  │ schema │ name │  params   │
╞══════════╪═══════╪════════╪══════╪═══════════╡
│ FUNCTION │ 18310 │ public │ plus │ (integer) │
│ RELATION │ 24576 │ public │ xx   │           │
└──────────┴───────┴────────┴──────┴───────────┘
(2 rows)
